It is reported that domestic institutions , corporate research into the field of sapphire substrate is divided into two blocks : one purchases abroad crystal growth furnace , in order from abroad crystal growth furnace get Sapphire Dan Changjing mystery . But surveys show that the use of foreign crystal growth furnace there are " low quality ", " yield is not high," and other issues , so often, and foreign suppliers of crystal growth furnace dispute . In addition, foreign not be advanced , large-size furnaces sold to Chinese enterprises, it is difficult to be eliminated from the old furnace to master truly excellent crystal growth furnace technology ; Second, through its own research and development of crystal growth furnace power . Rely on their own to overcome large-size sapphire Dan Changjing furnace research, risk , although larger, but " Relying on Ourselves " , usually only rely on their own in order to truly master the key technology . However, entrepreneurs should also be aware that their own research and development is no easy task , which requires abundant capital, research and development team together , continuous research firm determination perseverance and leadership .

GLII statistics show that only 2011 new LED sapphire substrate Dan Changjing furnace and the number of projects reached 26 , as of the end of the third quarter of 2012 the number of new projects the amount of 14 . Currently under construction Sapphire Dan Changjing project about two inches capacity sapphire substrate 100 million years , and the current actual market demand is just over 1000 million. Some of the epitaxial enterprises in the use of imported products , so the domestic severe overcapacity sapphire substrate .

Now sapphire substrate serious excess capacity , prices are low , many companies have slowed down the progress of investment expansion , direct impact on the sales of crystal growth furnace . " When asked about last year's sales , the crystal growth furnace company official said .

Customer sign a long single more, supply and demand situation has improved . The next three months sales and prices are on the rise . Insiders said that the downturn in the sapphire substrate prices are now so many companies lose money , are hoping this year epitaxial wafer fab capacity utilization can be improved, driven by a sapphire substrate sales and prices rise. But this year a good start can be maintained long , is a known issue.

Domestic institutions , companies should market demand , Sapphire Dan Changjing effort into research techniques , and finally in a short time has achieved some success : Size is small, lightweight ( 50 , 60kg ) Sapphire furnace Dan Changjing basic technical problems to be resolved . However, " there are unexpected storms ," when well- developed small size Sapphire Dan Changjing furnace can produce a large number of 2-inch wafers , a few developed countries abroad advanced technology can already produce a 4-inch wafers , MOCVD also gradually transition to using a 4 -inch wafer -based, so that the 2 -inch wafer prices never a shortage of $ 30 USD plunged 7,8 , then reproduction 2-inch wafers have been unprofitable. Spent a lot of manpower, material and financial resources , and finally overcome technical difficulties , yet the market has suffered " amulet ", which is undoubtedly a heavy blow , so many businesses slow down or even abandoned the sapphire substrate studies .

However, this does not mean that investment in technological research Sapphire Dan Changjing wrong ideas . Market shows that the sapphire substrate used has gradually transition from 2 to 4 -inch wafer -inch wafer . Drawn from the point of view of the same wafer , four 2 -inch wafer equivalent to a 4 -inch wafers, but the 2 -inch wafer can only sell 7-8 blocks dollars, while the 4 -inch wafers but can be sold at 60 , $ 70 . So, if put into research , small size, lightweight Sapphire Dan Changjing furnace, main outputs of 2 -inch wafer , then definitely no benefit at all, even at a loss ; if " drastic " continue to study the large-size , heavyweight sapphire crystal growth furnace , it is possible to obtain high efficiency as well as cost recovery . So some companies renewed hope , move on.

Side is the GT, ARC and other foreign manufacturers of extrusion, the other side is the sapphire substrate excess capacity, demand, prices have been falling , domestic long crystal furnace plant home is now caught in the middle for survival , and development . According to Engineering LED Industry Institute (GLII) recently released report, 2012 China mainland chip output of about 7.2 billion yuan , the average price fell about 32% , a decline of some products is as high as 50% .

GLII data show that in 2012 China mainland holdings from 2011 's 803 units to 917 units, but the capacity utilization rate is only about 30%, the boot was only about 50%. Low capacity utilization led directly upstream sapphire substrate and Sapphire Dan Changjing furnace corporate sales slump last year , the price all the way down . Currently , two -inch sapphire substrate market price has reached a cost of $ 7-8 near the line , more manufacturers in Taiwan and South Korea call for $ 6 of the "cheap ."
