OFweek Industry Research Center:4-inch LED Epitaxial Chips Will Become The New Darling of The Market

Recently , OFweek Industry Research Center released the " 2014 China LED epitaxial silicon market depth analysis and forecast report " ( hereinafter referred to as the "Report" ) , the " Report " on China LED epitaxial chip market has been in-depth analysis . Among them, the " report" on the size of the trend of LED epitaxial wafers made ​​a detailed analysis and concluded that : in 2014 , China's LED epitaxial chips will gradually change to 2-inch -oriented pattern, 4 -inch LED epitaxial LED epitaxial silicon chips will become business focus.

To improve the MOCVD production , LED manufacturers in the traditional way to increase production to increase the reactor , such as the production of 2-inch epitaxial wafer 19 furnace switch from 55 furnaces, stoves , but the cost will increase accordingly . With the development of technology, wafer sizes from 2 inches to 6 inches conversion , production increased by 30 %, but at no extra cost , relying on the large increase OFweek semiconductor lighting network MOCVD wafer size to improve yields, has become the most wafer production provider of choice.

Chip companies at home and abroad , the sapphire substrate wafer company uses only 8-inch maximum size , the Korean and Japanese markets are 4 inch, 6 inch, 8 -inch sapphire substrate used in half of Taiwanese companies are two half -inch 4 inch , the mainland market, its 2-inch main.

" Report" that began in 2014 , including three safety optoelectronics , BDO Runda, HC SemiTek etc. have started leading chip layout 2 inch to 4 -inch epitaxial silicon , the mainland market demand for large size is also increasing . 2013 Sanan Optoelectronics completed 2 inch to 4 inch slices percentage was 30 % in 2014 is expected to reach more than 70% ; BDO Runda LED wafer production line project is finished, will be capable of 1.8 million four inches LED epitaxial wafers capacity ; HC SemiTek Zhangjiagang planning sheet chips are all four inches , the project will be put into its new blue and green chip production capacity of 1995KK / month , equivalent to 4 -inch epitaxial wafers 3 50 million / month .

The main driving 2-inch to 4 -inch enterprise epitaxial chips for two reasons : first, to reduce costs, in 2-inch and 4 -inch piece of sheet yield is under the same premise , 4 -inch piece costs relative to the cost of 2-inch pieces Price reduced by 20 % -30 % ; second , 4 -inch sapphire substrate price decline accelerated. OFweek Industry Research Center data show that the current 4 -inch sapphire substrate prices have dropped the price level of 2011 2-inch sapphire substrate.
