At present, LED TV backlights dominate the market, and future lighting will bring another wave of enthusiasm. The reduction in the price of LED chips must first reduce the cost of LED epitaxial wafers, and the reduction of epitaxial cost needs to start at the same time as MOCVD yield and capacity. The stability and repeatability of the MOCVD machine determines the yield of the epitaxial wafer, while the MOCVD machine's increased capacity and cost reduction are based on equipment design.
The public data from MOCVD manufacturer Veeco shows that in the future, MOCVD yield, process and architecture improvements will make the cost of high-brightness LED epitaxy in 2014 at least four times lower than in 2009. The cost of a 2-inch high-brightness LED epitaxial wafer in 2009 will be 127 yuan, and will drop to 25 yuan in 2014.

At present, the production capacity of both domestic and Taiwan epitaxial wafer factories is fully loaded. Among them, domestic and foreign extension factories basically do not sell epitaxial wafers. They are basically used for their own production of chip exports. Some enterprises only supply a small amount of products. GLII data shows domestic chips. The processing plant is mainly ordered from Taiwan's New Century Optoelectronics, Guangcai Optoelectronics, Chi Mei and other Taiwan second-line epitaxial plants. Considering the installation and commissioning period of the MOCVD machine and the digesting time of the signed orders, the shortage of domestic and international extensions will continue. GLII estimates that this situation may improve in the third quarter of 2011.
As of September 2010, domestic manufacturers ranked first in Sanan Optoelectronics' monthly production capacity of 100,000 epitaxial wafers, followed by Shandong Huaguang, Silanwei, Hualei and Huacan (see the current magazine list for detailed ranking) . GLII statistics domestic manufacturers of epitaxial film total monthly production capacity of 280,000, by the end of this year this figure will grow to about 400,000.
In the first half of 2010, due to the tight supply of global LED chips, some Taiwanese extension manufacturers increased the price of epitaxial wafers by 20%-35%, the industry average gross profit margin exceeded 50%, and the net profit margin exceeded 40%. GLII predicts that as LED backlight demand begins to stabilize and a significant number of MOCVD machines are in place, the price of epitaxial wafers will start to change from the third quarter, but the sapphire substrate capacity limit will not exceed the previous price. The magnitude of the increase. The tight supply of global epitaxial films will ease after the second quarter of 2011.
