LED elements required to enhance the brightness, LED factory to improve the use of patterned sapphire substrate volume, in 2014 many patterned sapphire substrate plant plans to significantly expand its production capacity, and due to 4-inch high demand, so manufacturers will migrate to the new 4-inch production line development.

In the two sides patterned sapphire substrate plant in Taiwan plant expansion moves in the most positive, DIGITIMESResearch statistics, in 2014 the first quarter of Taiwan patterned sapphire substrate average monthly production capacity of 2.19 million (2 inches calculation), 4th 2014 quarter of the average monthly production capacity to 4.27 million, and the quarterly rate of increase of over 20%.

If the observed degree of industrial concentration patterned sapphire substrate plant in Taiwan, the two plants by 2014 Rui Jie and Zhao than weighing approximately 50%, while the top five manufacturers concentration of 75.3% by the first quarter of 2014, will increase the first 81.3% in the fourth quarter, the industrial concentration before further calculation if 10 great cause, and by 95.6% in the first quarter of 2014, will increase to 97.6% in the fourth quarter.

2014 As cross-strait 4 inch LED epitaxial plant capacity to enhance the proportion of the 4-inch sapphire substrate patterned high demand, DIGITIMESResearch in consideration of each quarter capacity utilization, the number of new capacity, patterned sapphire substrate under outsourcing and other factors . Both sides of the first quarter of 2014, 4-inch sapphire substrate patterned average monthly demand of 462,000, the third quarter will reach a peak of 579,000 in the fourth quarter due to the off-season to enter the industry, the demand will decrease.

In the strait 4 inch patterned sapphire substrate supply, Taiwan patterned sapphire substrate plant also supply to the mainland industry, relative, mainland patterned sapphire substrate plant to supply the amount is not high compared with Taiwan factory. Also, consider the industry has to overcome the problem of yield 4 inch conversion process, so the first quarter of 2014, the two sides can supply 4-inch sapphire substrate patterned average monthly volume of 332,000, the second half of each quarter to March 2014 both the amount will be 544 000, 643 000. If both sides of the above 4-inch LED epitaxial plant needs a few pieces compared to 2014 can be found in the third quarter of 4-inch sapphire substrate patterned tight supply situation is still showing.

In the patterned sapphire substrate prices, the 2014 full year rose 4 inches more obvious by $ 51 in the first quarter, will rise to $ 55 in the fourth quarter, an increase of 7.8%, mainly due to price increases by the sapphire crystal rod, the also due to the 4-inch LED epitaxial plant patterned sapphire substrate demand due to warming; As 2-inch substrates is presented edged situation, forecast full-year 2014 growth rate will be 4% in the fourth quarter will be watching $ 13.

Late last year, Apple 5S in HomeButton camera key and sapphire are used after the protective cover, effectively digest the sapphire production capacity, the end of last year, even as some international companies in the state of technology upgrades and maintenance shutdown, once brought sapphire supply and demand The short-term stress, sapphire crystal rod prices also rose for the first few years, once driven ingot rose to five dollars per millimeter price, and established industry gradually pulled away from the operating sapphire valley.

This year, the two sides of sapphire plant starts production capacity and expansion moves frequently, precisely Looking for the opportunity next year, but, due to the future application of surface structure also followed different, although the environment favorable for the sapphire industry, but manufacturers Competitiveness is also expected to appear shuffle along, sapphire big apple industry, but do not touch or do not touch the manufacturers, this time, I am afraid that is not easy in 2010 without irrational exuberance sapphire factory full scene appears.

Sapphire from the entire industry value chain, in general, the whole industry chain crystal growth is the most valuable part, accounting for about fifty-five% sapphire substrate costs, other cutting, grinding, polishing and other processes plus, then about 40 percent. Among these ingot production of high barriers to entry, and volume production is not easy, it is the key to the whole industry chain.

Therefore, once a large number of non-LED optical applications increase, the ingot is indeed likely to arise due to stock prices, research coordinating body estimates that next year ingot least five percent gap between supply and demand, as many as three percent.

The actual current situation, despite the majority of the ingot plant fear not become Apple's suppliers, but it can because a lot of new products and the resulting optical crystal rods inadequate supply, and thus indirectly benefit, higher product quality and quantity of grain rod plant, expected to be the biggest winner, domestic energy production ingot manufacturers, including Acme, Jia Jing Branch fastest at the end of this year, will be able Looking wave of new business opportunities.

In fact, Chinese manufacturers regardless of sapphire production yield or production technology, has the potential to catch up international companies, with Chinese manufacturers in the production costs than U.S., Japan and other developed countries manufacturers more competitive, China Sapphire Ingot Plant If production capacity next year to accelerate the release of global sapphire crystal rod plant will accelerate shuffle.

Can be established, the new generation of Apple's product applications locked in cooperation with GTAT, Apple has actually won most of the country, due to the sapphire ingot production in addition to the requirements of professional and high-technology equipment, the investment funds are also high, with Unlike the crystal growth manufacturing and processing segment, is a high technical threshold and barriers to trade, for the great challenges of the new entrants. Future development of the ingot plant is bound to the bigger, with a production scale strength of the manufacturers, have a chance in the next wave of fanfare rising tide of sapphire.

After several years of significant growth year after the protective glass market growth rate will gradually slow down. However, the recent interest in the application end brands and materials to improve the protection of the glass market has played the role of stimulation and change again.

According NPDDisplaySearch latest "touch protective glass panel report," although total shipments in 2013 to protect the glass surface years, compared with an increase of 37% in 2012, but is expected to increase the surface area of ​​total shipments in 2014 will slow, the magnitude of the In only by about 17%.

NPDDisplaySearch Xie Zhongli, research director, said: "With the end of the main application of increasingly sophisticated needs, protect the glass market competition becomes increasingly fierce. However, the future of sapphire material on the use of high-end smartphones, slow growth will be a breakthrough. "

Considerations on production costs, the current smart phone brand sapphire material only protective cover for the camera and fingerprint recognition component above. However, in the past two years, Apple actively patented sapphire material and layout processing and supply chain, Apple as a protective sapphire glass should have been, in contrast, is expected to adopt as early as next year. In addition, Apple to GTAdvancedTechnologies (GTAT) provided approximately $ 578 million in advances for building Apple's own supply chain. And GTAT recently acquired Hyperion, and cooperation with EVGroup special thin paste layer technology development.

Xie Zhongli said: "Apple seems to sapphire as a strategic material for future projects. But in the long run, the application might not be dependent on conventional sapphire material supply chain, but rather to establish a competitive threshold through its own patents, technology and supply chain. "

In addition to Apple, other brands such as Samsung and LG are also expected to adopt new materials sapphire or on some high-end limited edition models. Xie Zhongli added: "For example, Samsung in the latest GalaxyS5 aircraft launched a special decorated with Swarovski crystals limited edition cover. Material will become the flagship model differentiation and value approach. "

Global market research firm TrendForce's green energy research division LEDinside recently released "2014 Global Market Report sapphire substrate," noted the upcoming end of 2014, Apple's iWatch will have the opportunity to adopt sapphire cover. iWatch sapphire table cover expected 6 percent in 2014 will reach the global market demand for sapphire. If the 2015 sales figures of the market's most optimistic estimate of sixty million, in 2015 will account for 27% of global consumption of sapphire substrate, while the total consumption of the overall sapphire substrate will be compared to 2014 will grow to more than double , up to 129%.

Sapphire cover will likely be applied APPLE wearable appliance

According to LEDinside investigation, the upcoming debut of Apple iWatch at the end of the cover will have the opportunity to import sapphire material. Since sapphire material has abrasion, scratch properties, so the traditional fine watches using sapphire cover has been for years. But market demand handheld device applications is enormous, the traditional annual market size of fine watches only about one million compared to far, and flame fusion of traditional table cover past used Sapphire Dan Changjing process has been unable to cope huge market demand handheld appliance. According to iWatch specification, you must use special specifications sapphire ingot manufacturers only able to meet the design requirements for subsequent processing, which also explains why Appple requires active Provisioning sapphire industry supply chain.

iWatch sales figures will determine the 2015 sapphire substrate industry supply and demand

It is understood that the first launch of iWatch APPLE there will be men and women watches, the cover will fully cover the use of sapphire, respectively, male models female models 1.33 inch and 1.66 inch. Since the end of 2014 was launched iWatch, so if in 2014 there were five million iWatch demand, will occupy 6% of the estimated demand for sapphire market. As iWatch 2015 total shipments divergent figures, the current number of learned iWatch in the first quarter of 2015 also stocking up the thirteen million. If the sales situation than expected, the market's most optimistic forecast shipments will have the opportunity to sixty million. Overall demand for sapphire will cover 27% of the world will account for the amount of the sapphire substrate, while total consumption overall sapphire substrates will grow to more than double compared to 2014, reaching 129%. Therefore, the degree of consumer acceptance iWatch important factors that will determine whether the sapphire substrate industry in 2015 will supply tight.

NPDDisplaySearch research director Xie Zhongli said that with the main application side (such as smart phones and tablet PCs) and the increasingly sophisticated needs, protect the glass becomes increasingly fierce market competition, not only makes the surface area of ​​the slowdown in the growth rate of shipments, while Price has been decline. However, the future of sapphire material on the use of high-end smart phones, may bring changes to protect the glass market, especially price and supply chain.

According NPDDisplaySearch latest "touch protective glass panel report," pointed out, (TouchPanelCoverGlassReport), although the total shipments protective glass (including glass and plastic materials) between surface area in 2013, compared with an increase of 37% in 2012, but is expected in 2014 The total surface area of ​​growth will slow down shipments magnitude will only be increased by approximately 17% compared to 2013.

For the production of cost considerations, the current smart phone brand, especially apples, sapphire material will be used only to cover the camera and fingerprint recognition devices above. However, in the past two years, Apple actively on sapphire materials and processing related patents such as sapphire engagement with the paste layer and the layout of the supply chain, Apple as a protective sapphire glass should have been ready to come out.

In addition to Apple, other brands are also new material on sapphire or showing interest. Given the price considerations, the glass will still be a major application of protective glass material, but sapphire can be designed in a number of high-end or limited edition models, as a marketing tactic, such as Samsung's latest flagship models GalaxyS5 on launched a special decorated with Swarovski crystals limited edition cover, smart phone features in today's increasingly sophisticated materials will be differentiated and value approach.

LED energy-saving applications either in or on the lighting effects have energy-saving lamps, incandescent lamps, halogen lamps, and other traditional lighting can not match advantage. Precisely why, LED lamps become a trend to replace traditional lighting.

Compared with the whole point of tungsten, energy saving lamps, incandescent and other traditional lighting of the light, only fixed-emitting LED light source, its light angle limitations will not be able to meet the needs of indoor lighting, but also affect people's physiological and psychological state. How to overcome this defect LED light source, an important direction for many people in the industry think, is, therefore, the concept of 360-degree LED thus germination.

360 degree light emitting angle of its products and the convergence of traditional lighting products are sought after in the industry. In fact, several years ago "LED360 degree light" concept has been put on the agenda of the enterprise. Up to now, the major well-known show, 360-degree LED lamps have been the highlight of the show was business as highlight.

360 degree LED stands for "light-emitting 360-degree beam space LED", who can issue a uniform "ball of light" LED element to the surrounding space, can be called "360-degree LED". Compared with ordinary LED, 360-degree LED light emitted by countless beams are continuous, uniform, soft light emitted into space in all directions, a spherical light effects with conventional bulbs identical.

On the other hand, is now available in the market as well as corn-based LED bulb-type LED bulbs frosted lamps also belong to 360-degree angle of light, but compared with these lamps, LED lamps light 360 degrees softer, more uniform illumination, these The advantage is that these two products can not match. Probably the majority of the lighting business took a fancy to this opportunity, and thus have R & D 360 LED lamps.

According to the reporter survey found that 360 degree light fixtures now mostly done by the LED filament. The 360 ​​most luminous lighting production applications category is LED bulb, candle lights and a small part of the LED lamp.

On LED lamp, since the LED light source emitting directional characteristics, light angle straight tube LED lamps generally only about 120 degrees, so that the sides and in the back of a certain dark areas, will affect the overall lighting effects to a certain extent and environmental aesthetics.

Therefore, many enterprises in order to achieve a more uniform and completely replace the effect of energy-saving lamps, will focus on research and development to expand the light angle, there are already companies said light angle it straight tube LED lamps can be 360 ​​degrees the whole point of light.

As for the LED bulb and candle lights, Park Kun lion overseas sales director recently revealed that 360 bulb mainly to replace the traditional light bulb concept design, brightness and angle of the more comforting.

It is understood that the industry made a 360-degree lighting companies have done a better IMC Optical source Lei, Zhou optoelectronics, Bodhisattva Shengyuan, Bo lion optoelectronics.

In the R & D level, the whole point of 360 degrees by the producers sought luminescent lamps, while the retail market this product in the terminal's influence also not be underestimated.

Recently, the reporter visited the Shenzhen major lighting stores found that 360 degree light fixture has been moved in the store, this feeling when reporters investigating Huaqiang North LED Trading Center is particularly evident. Throughout the stores, accounting for 360 degree light bulb and candle lights up, especially candle lights, glowing candle light 360 degrees account for at least 20% of the entire store LED candle lamp.

From the quantitative point of view on the whole, this proportion is not large. But to know that last October, when the reporter visited the store, but also it is difficult to see almost 360 degree light products. Thus comparison, this growth rate is quite fast.

"After this year, Europe to promote 'ban white' policy, the corresponding traditional incandescent lighting can not re-enter the market, while there are still some consumers nowadays have a soft spot for the traditional incandescent, 360 degree light bulb and other products is based on this. "General manager 荣万佳 lighting Shenzhen 阮青海 to Engineering," said LED lighting channels "reporter.

It is understood that 360 degree light bulb is based on the basis of incandescent lamps produced. Although this product looks very "tall on," but in fact, this use of LED filament column design produced by the LED light bulb technology is not difficult. It is understood that the production of large-angle light-emitting lamps sinking mainly through the chip to expand through all light-emitting angle and pipe materials are two ways to achieve this.

With candle lamps, for example, two columns in series LED filament 360 can be designed to emit light 1.8W candle lights, LED brightness can be the equivalent of 8-10W incandescent lamp.

Although the 360-degree light bulb is the best alternative to incandescent lamps, but Ruan Qinghai simultaneously cautioned: "As a 360-degree product restricted technology, general wattage can not do too much, or else the heat reach, product life affected. "

As Ruan Qinghai said, the reporter through the investigation found that the current market 360 degree light bulb generally not more than 3W.

"Nowadays to do 360-degree light is not difficult, it can be done with a transparent substrate. However, the heat lamp gas filled cavity, so this premise must be small enough lighting power, if it is a 1W lamps, measured by aging, heat is no problem, but once power is too large, will certainly affect the life of the lamp. "Lighting engineer Xu told reporters.

Precisely because, at present, only 360 light-emitting low-wattage lamps to replace incandescent lamps.

In the LED industry, China's own innovative silicon substrate LED technology known as following the addition of silicon carbide (SiC) LED technology, LED sapphire substrate technology third technical route, which broke the Japanese and European manufacturers formed LED strong patent barriers, have complete independent intellectual property rights, the freedom to go abroad.

Difficult! This is the art will understand LED LED material on the growth of a first silicon substrate reaction. Difficulties children? Before 2004, 30 years of research does not address the silicon substrate and the GaN lattice mismatch and thermal mismatch problem, people can not get quality GaN light-emitting film.

Good! LED technology is a silicon substrate LED industry for decades route coveted technology roadmap. Fortunately Where? If we can break through the silicon substrate LED technology problems, to achieve mass production of large size, can significantly reduce the cost and accelerate the arrival of the era of LED lighting!

Silicon substrate LED LED industry technology roadmap is the dream of the technical route, but due to technical difficulties, so most remain in the water phase of the test laboratory. Arduous to activate the mountains - until 2004, in a humble laboratory Nanchang University, the silicon substrate LED blue chip pioneered breakthrough silicon substrate LED technology to achieve a disruptive breakthrough in epoch-making milestone in the history of the world LED.

Now, over the past ten years, LED technology unless the silicon substrate exists only in the laboratory of history. In the effort to support GSR Ventures and a number of venture capital, the already developed into optical crystal, crystal and energy-efficient lighting in the 10's the whole industry chain of industrial clusters, industrial chain sales reached 1 billion in 2013 RMB 2014 is expected to reach 2.5 billion yuan.

Technology features, market segment leader decided

Silicon substrate LED chip is a vertical structure, the current spread evenly, large unit area can carry current densities, combined with the cooling effect of the silicon substrate is much better than the sapphire substrate, reliability, suitable for the manufacture of high-power LED products can be widely applied At the high reliability requirements of lights, tunnel lights, spot lights and other outdoor lighting.

Its chip is a single electrode, the chip size can be very small, because a few dozen electrode line, with high reliability obvious advantages in digital products, high-density areas such as indoor display, many German brand car dashboards are LED chips are made using silicon substrate backlight.

Silicon substrate LED chip is flip-chip peel, single light, so the product has an easy to control light direction features in car headlights, searchlights, bike lights and other fields has obvious advantages.

Its one-sided glowing light characteristics determine its uniform, good quality, and thus require high quality light products, such as high-end mobile phone flash, monitoring facilities, fill light for galleries, jewelry stores, vegetable shops and other places spotlights, etc., with a silicon substrate LED chip is the best choice.

In these areas, the market capacity of at least $ 20 billion a year, and the gradual growth of the silicon substrate LED products in these market segments have a strong competitive advantage.

Patent protection, future patent litigation against international giants "amulet"

If the subject of his country's Blu-ray DVD lessons did not alert us, then repeat the PV of Shame should make us sobering. Foreign LED manufacturers Fangshuiyangyu effort has reached a pinnacle, with the growing size of the domestic LED, LED want to avoid patent siege foreign giants, with existing technology, talent and team probably "extremely difficult."

Technological innovation is the LED chip enterprises in market competition, then the patent is technological innovation "protection." From a technical breakthrough began LatticePower on silicon substrate LED technology as the core, covering the epitaxial growth, chip manufacturing, packaging and application of patent network rolled out in Europe, America, South Korea, Japan and other countries and regions LED. With its own LED upstream core patent is a long drive home market of the weapon, but also the future of the international giants talisman against patent litigation.

Build support platform, the silicon substrate LED technology innovation accelerator

Although the domestic LED enterprises are well versed importance of technological innovation, but innovation requires research and development platform, incubator, funding platform, personnel platform systemic support.

Obviously, the charm of the silicon substrate LED technology has attracted many outstanding talents at home and abroad gather LatticePower, industrial clusters have been approved by the State Ministry of Science has a silicon LED Engineering Research Center and the National Development and Reform Commission State and Local Joint Engineering solid state light source Technical Center these two strong technology platform, forming a vertically integrated epitaxial materials, chip, package, and application development, coupled with the silicon substrate LED industry chain enterprises jointly many famous universities and research institutes, as silicon substrate LED technology innovation and research to create a powerful platform and technology incubator.

Meanwhile, attracted the Jinsha River, Temasek and a number of well-known international and domestic venture capital fund of funds platform, especially focused on investing in established companies Seong capital Nanchang, built a three-dimensional solid financing platform.

LED industry development and look forward to the large size of the silicon substrate LED technology matures

In no other disruptive technology before, silicon substrate LED technology is one of the most effective ways to reduce the cost of LED. One of the most important means is to use 6-inch and above large-size substrate, epitaxial material.

First, the silicon substrate material is cheap, especially as size increases, the price per unit area continuously decreased; Second, because the effect of the outer ring, the effective number of particles per unit area of ​​the chip is greatly increased. Once again, the large size of the integrated circuit wafer manufacturing technology has been very mature, large-size silicon substrate LED chip technology can learn and mature integrated circuit technology production lines, automated mass production, 6-inch productivity and present 2 inches can improve compared to 11-12 times, effectively reducing the chip cost. Sharp decline in the cost of LED lighting will encourage faster spread.

Currently, in addition to optical crystal, Cree, Osram, Samsung, Lumileds, Toshiba, Epistar and the United States and other international first-tier manufacturers are Micron generous investment in research and development of LED technology, the silicon substrate in order to achieve technological breakthroughs on a silicon substrate. Its release signals may be able to reduce a lot of people questioned on the silicon substrate LED technology. Of course, this also makes a leader LatticePower feel tremendous pressure. It is foreseeable that, following LatticePower production and continue expansion after the silicon substrate LED technology roadmap camp will be increasing.

For decades, the global LED technology follows the "HAITZE" law, has undergone a tremendous change, LED luminous efficiency increased from 100lm / W to 260lm / W (experimental), getting closer to the LED light efficiency limit. When the light efficiency is not the only goal of LED chip manufacturers to pursue, regardless of technology LED sapphire, silicon carbide or silicon substrate LED technology LED technology, cost competitiveness between them when the real Sword.

Aladdin Jury Award, South China Normal University professor, renowned optical experts Wen Shang Sheng said: 'LatticePower company is the second after Japan's sapphire substrate CREE LED technology, the United States CREE company SIC LED technology, the global LED third pole art - silicon substrate LED technology leader, but also China in the field of LED technology most enterprises the right to speak. The latest development of the next-generation silicon substrate GaN-based LED chips, in addition to the traditional vertical structure outside the chip technology, innovation in chip evenly excavation multiple "through holes Via", can make the N-type metal uniform LED chip embedded inside. The benefits of this new technology in two ways: First, the "through-holes Via" uniformly distributed inside the chip, the chip current injection also uniformly distributed in the N-GaN, effectively eliminating the current congestion phenomenon, ease Droop effect, improving light efficiency. Second, to overcome the chronic region of traditional LED light emitting quantum well (MQW) external to the chip by the N electrode of the light emitting block, can significantly improve the light extraction efficiency of the chip. By applying this new technology to the company's optical efficiency crystalline silicon substrate LED chips reach 150lm / W, as the world and the only one can reach far beyond the requirements of lighting applications that can scale production of high-power silicon substrate bottom LED chip.

No dream, why afar?

Optical crystal silicon substrate LED technology in a decade of painstaking research institute's breakthrough is LatticePower team to dream for the end to the struggle as a starting point and the result of tireless work. By LatticePower co-founder, CEO Dr. Wang Min as saying: LatticePower is ideal for business, because there is an ideal, so there attract many local and overseas talent cohesion; Because ideals, so the team can refuse flashy, silently insist years; Because ideals, so you can face the future, goes away.

Chemical properties of sapphire crystal is very stable, with a high melting point, high hardness characteristics, and with good light transmission, good thermal conductivity and electrical insulation, and mechanical mechanical properties, wear resistance and excellent resistance to erosion and other optical and physical chemical properties.

Therefore, sapphire microelectronics and optoelectronics industries extremely important basic materials, widely used in semiconductor, microelectronics, optoelectronics, information display, and many other fields optical communications, laser, precision machinery, defense and military. With the development of science and technology, the size of the sapphire crystal material quality have made new demands. Now, with the rapid development of semiconductor lighting and other emerging applications, low-cost, high-quality, large-size sapphire crystal market demand is rapidly expanding.

Since 1885, made a sensational time, "Geneva Ruby" by the Fremy, Feil and Wyse use hydrogen flame to melt the powder and potassium dichromate natural ruby, sapphire grown artificially studies to date more than 100 years of history. One hundred years, in order to meet the scientific and technological development and industrial production for the special requirements of sapphire crystal quality, size, shape, in order to improve the yield of sapphire crystal, utilization and reduce costs, the growth of sapphire methods and theories research has never stopped, its equipment and technology are the last century has made rapid development, so far, sapphire industry already has a high technical level and greater production capacity, ingot sizes from 2 inches to expand to the current 12 inches, whom ancillary equipment and materials also will be rapid development.

Currently various crystal growth technology has applications in the market, and the crystal purity of 99.99% can be reached, but due to different growth mechanisms, but also there are some shortcomings and limitations, difficult to meet future large-size sapphire crystal high-quality, low-cost development needs. For example, flame melting method, a Czochralski crystal growth method such as the quality and size are restricted; heat exchange method, temperature gradient method and the like Kyropoulos method requires a large helium coolant; temperature gradient method, the Kyropoulos Growth sapphire crystal blank requires a high temperature annealing process, subsequent processing of the blank process more complicated and costly.

But from the point of view of market share, Kyropoulos currently in a dominant position, the world's largest manufacturer of sapphire Rubicon America and Russia Monocrystal are produced using this technology sapphire crystal, in addition to including the Beijing-crystal optical sapphire, including several Chinese manufacturers are also using this method. Using this method produced sapphire crystal over 50% of global production, including a sapphire substrate used in semiconductor lighting more than 70% this production. Temperature gradient method is the main technology used by South Korean companies, the potential of this technology to produce low-density, high-quality ingot, the crystal size is relatively small and limited long grain shape, is also occupy a certain market share.

Chemical properties of sapphire crystal is very stable , with a high melting point (2050 ℃), high hardness ( Mohs hardness of 9 , second only to diamond ) characteristics, and with good light transmission, thermal conductivity and electrical insulation, as well as good mechanical mechanical properties, excellent wear resistance and anti- erosion and other optical and physical and chemical properties.

Therefore , sapphire microelectronics and optoelectronics industries extremely important basic materials , widely used in semiconductor , microelectronics, optoelectronics, information display, and many other fields optical communications, laser , precision machinery , defense and military . With the development of science and technology, the size of the sapphire crystal material quality have made new demands. Now , with the rapid development of semiconductor lighting and other emerging applications , low-cost, high-quality, large-size sapphire crystal market demand is rapidly expanding.

Since 1885, made ​​a sensational time , " Geneva Ruby" by the Fremy, Feil and Wyse use hydrogen flame to melt the powder and potassium dichromate natural ruby , sapphire grown artificially studies to date more than 100 years of history. One hundred years, in order to meet the scientific and technological development and industrial production for the special requirements of sapphire crystal quality , size, shape , in order to improve the yield of sapphire crystal , utilization and reduce costs, the growth of sapphire methods and theories research has never stopped , its equipment and technology are the last century has made rapid development , so far, sapphire industry already has a high technical level and greater production capacity , ingot sizes from 2 inches to expand to the current 12 inches, whom ancillary equipment and materials also will be rapid development .

Currently various crystal growth technology has applications in the market , and the crystal purity of 99.99% can be reached , but due to different growth mechanisms , but also there are some shortcomings and limitations , difficult to meet future large-size sapphire crystal high-quality, low-cost development needs. For example , flame melting method, a Czochralski crystal growth method such as the quality and size are restricted ; heat exchange method, temperature gradient method and the like Kyropoulos method requires a large helium coolant ; temperature gradient method, the Kyropoulos Growth sapphire crystal blank requires a high temperature annealing process , subsequent processing of the blank process more complicated and costly .

But from the point of view of market share , Kyropoulos currently in a dominant position , the world's largest manufacturer of sapphire Rubicon America and Russia Monocrystal are produced using this technology sapphire crystal , in addition to including the Beijing- crystal optical sapphire , including several Chinese manufacturers are also using this method . Using this method produced sapphire crystal over 50 % of global production , including a sapphire substrate used in semiconductor lighting more than 70% this production . Temperature gradient method is the main technology used by South Korean companies , the potential of this technology to produce low -density , high-quality ingot , the crystal size ( diameter and height ) and long grain shape relatively limited small, currently occupy a certain market share . Guided-mode method mainly by Japanese companies to learn and use , the product is basically supply the Japanese market , in addition to guided-mode method Ukraine also produces crystal growth furnaces.
