Veeco: to 2014, the cost of high brightness LED epitaxy is reduced by at least four times - China International LED market trends Forum lecture Report

Future LED chip prices will have a larger decline in space, general manager of Greater China Wang Keyang Veeco in ledinside held in Guangzhou "Chinese international LED market trends Forum" said Veeco will yield by MOCVD, and improve the process architecture, the 2014 high brightness LED epitaxial cost decreased compared with 2009 at least four times. 2009 high brightness LED epitaxial wafer cost $1 / square centimeter, in 2014 will drop to $0.2 / cm2.

Mr. Wang Keyang said that the current LED TV LED backlight lighting market at present, brings another wave of peak. Reduce the price of LED chips must first reduce the LED epitaxial wafer cost, and reduce the cost of the extension rate and capacity at the same time to need from. MOCVD stability and repeatability of the machine determines the yield rate of epitaxial wafer, MOCVD production capacity and reduce the cost of the design from the start. Veeco's K series GaN platform, has been verified by LED large mature technology can support the extension of mass production. Veeco K465i has formed 2 inch and 4 inch production main models, it provides customers with the best investment protection and recovery. The following figure is the main indicator of the Veeco MOCVD device.

The main advantage of Veeco MOCVD machine:

1) production verification based on K platform

2) TurboDisc? Technology to ensure the reaction chamber clean and free of particulate formation abnormal efficient operation and production capacity

3) Uniform FlowFlange? Rapid design process optimization and equipment technology excellent uniformity and repeatability of simple and robust maintenance after the rapid resumption of production capacity

4) automation automation platform for high yield and low cost possible

Using "flexibility" outsourcing production of MOCVD equipment, according to the change of market demand increase or decrease of production planning, according to the 2010 Veeco MOCVD production capacity will exceed 300 units, which in 2010 Q3 production capacity reached 100, in 2010 amounted to 120 Q4.

Reliability MOCVD equipment mainly from the mean time between failures (MTBF), the average cleaning time interval (MTBC), mean time to repair (MTTR) three aspects to consider, at the same time, and the process control is the key production line equipment. Veeco will reduce the cost of high brightness LED epitaxy by at least four times through the improvement of MOCVD yield, process and architecture.

LEDinside view:

In the global LED industry to LED industry technology progress very quickly, improve the luminous efficiency of the speed and reduces the cost of related products are in the accelerated speed. The price is one of the important factors restricting the further promotion of LED products, Veeco will reach the performance improvement of MOCVD machine to reduce the high brightness LED epitaxial wafer cost reduced from LED high brightness Veeco epitaxial wafer cost planning, cost and future LED products of the larger space exploration, LED product price with the increase of LED the application of the market continues to be developed, to promote LED industry development.
