In the future, the price of LED chips will have a large room for decline. Wang Keyang, general manager of Veeco Greater China, said at the "China International LED Market Trend Summit Forum" held in Guangzhou, Veeco will pass MOCVD yield, process and architecture. Improvements have reduced the cost of high-brightness LED epitaxy by at least four times in 2009 compared to 2009. In 2009, the cost of high-brightness LED epitaxial wafers was $1/cm2, which will drop to $0.2/cm2 in 2014.
Mr. Wang Keyang said that LED TV backlights currently dominate the current market, and lighting will bring another peak. The reduction in the price of LED chips must first reduce the cost of LED epitaxial wafers, and the reduction of epitaxial costs needs to start at both yield and productivity. The stability and repeatability of the MOCVD machine determines the yield of the epitaxial wafer. The increase in the capacity of the MOCVD machine and the cost reduction are based on the design. Veeco's K-series GaN platform has been proven by LED manufacturers with proven technology to support epitaxial mass production. Veeco's K465i has been built into 2" and 4" production models, which provide customers with the best investment protection and recycling. The figure below shows the main indicators of the Veeco MOCVD equipment.
The main advantages of the Veeco MOCVD machine:
1) Production verification
Based on the K-Series platform
2) TurboDisc? technology
Ensure that the reaction chamber is clean and free of particles
Abnormally efficient operation and production capacity
3) Uniform FlowFlange? technology
Excellent uniformity and repeatability
Simple and robust design
Rapid process optimization and rapid resumption of production after equipment maintenance
4) Automation
Fully automated platform enables high throughput and low cost
The use of "elastic" outsourcing model to produce MOCVD equipment can increase production or reduce production according to market demand. According to the planned 2010 Veeco MOCVD capacity will exceed 300 units, of which 2010 Q3 capacity will reach 100 units, and in 2010 Q4 will reach 120 units.
The reliability of MOCVD equipment is mainly considered from three aspects: mean time between failure (MTBF), mean time between cleaning (MTBC) and mean time to repair (MTTR). At the same time, inter-equipment matching and on-line process control are the key to mass production. Veeco will reduce the cost of high-brightness LED epitaxy by at least four times through MOCVD yield, process and architecture improvements.
LEDinside view:
Under the efforts of the global LED industry, the LED industry has made rapid progress in technology, and the speed of improvement of luminous efficiency and the speed of reduction of related products are accelerating. The price aspect is one of the important factors restricting the further promotion of LED products. Veeco will reduce the cost of high-brightness LED epitaxial wafers by improving the performance of MOCVD machines. From the perspective of Veeco's LED high-brightness epitaxial wafer cost reduction plan, future LEDs There is still a large space for product cost exploration. The improvement of the cost performance of LED products has led to the continuous development of the LED application market, which has led to the development of the LED industry.
