by any other electronic product. Along with growing LED brightness and falling prices, the share of LED in general lighting field is expected to be increased greatly; the general lighting market is of huge potential with the market size reaching US$100 billion. Promisingly, the LED market can reach US$20.4 billion in 2012.
The global LED market falls into three camps.
The 1st camp is represented by Japan, Europe & America. It possesses high-class technologies, abundant patents and has been dedicated to the UHB-LED field for many years, aiming at both general lighting and automotive lighting markets. The global Top 5 LED giants all belong to this camp. These are Nichia, Toyoda Gosei, Lumileds, Cree and Osram. Other companies in this camp include Toshiba, Panasonic and Sharp. Japanese enterprises give a little attention to the LED in the backlight of consumer electronics, while European and American enterprises show no interest at all.
Manufacturers in South Korea and Taiwan form the 2nd camp. With integrated consumer electronics industry chain and interest in the LED for the backlight of consumer electronics, they are experiencing high-speed growth despite the gap with European and American enterprises in technology.
The manufacturers in the Chinese Mainland belong to the 3rd camp. These small firms are scattered, and use low level technologies. For example, there are not more than 5 packaging plants in South Korea, while in the Chinese Mainland, there are nearly 1,000. Many of these deal with resin packaging requiring minimal technology and only a few are engaged in more sophisticated SMD packaging. The annual revenue of all these manufacturers fails to reach that of Everlight, the leading enterprise in Taiwan.
There are also large discrepancies between Everlight and South Korean manufacturers. The technologies possessed by manufacturers in the Chinese Mainland are low-level and many of the manufacturers produce quaternionic green/ yellow LEDs. These are mainly applied in outdoor landscape, decoration or advertisements.
Mainland China is the world’s largest production base of consumer electronics, but the purchasing
rights are centralized in the hands of Taiwanese and South Korean manufacturers. As a result, the mainland manufacturers can only see the rapid development of the LED market in consumer electronics field but cannot benefit from it. As for the general lighting field, it is more beyond their reach due to their primitive technologies.
The mainland manufacturers cannot share the high-growth LED market, but they have the highest investment enthusiasm and so LED projects start up everywhere.
Large quantities of MOCVD equipment have been bought in and the LED project in Wuhu alone needs more than 200 sets of MOCVD equipment. A single set of MOCVD equipment possesses over 2,000 parameters, so, it is not so easy to produce qualified products. In addition, there are numerous thresholds for LED patents, and lack of vigilance could cause trouble with infringements. Some enterprises, especially Nichia, are never bored with patent lawsuits.
Silan orders 6 Aixtron CRIUS II reactors for UHB LEDs
Chinese firm hopes the MOCVD systems will help satisfy surging blue and green LED demands.
Aixtron has received an order for six CRIUS II 55x2-inch configuration deposition systems from Hangzhou Silan Microelectronics or ‘Silan’. The Hangzhou, PR China based company, placed the order in the second quarter of 2010 and will take delivery of the systems over the fourth quarter 2010 to first quarter 2011 period.
The systems will be used for the volume production of GaN ultra-high brightness (UHB) blue/ green LEDs. The local Aixtron support team will commission the new reactors at the company’s facility in Hangzhou, China.
Jiang Zhongyong, General Manager at Silan Azure, commented, “We are looking to carry out a major capacity increase for our nitride LED wafers so naturally we turned to Aixtron. Their new generation CRIUS II systems have demonstrated major improvements such as higher growth rates, high pressure growth and the more than doubling of
