The development of LED epitaxial chips in China

Chip LED epitaxial growth and manufacturing process will directly affect the performance and quality of LED terminal products, is the core part of LED in the production process, the technology development level directly determines the degree of penetration and coverage of downstream applications. The development of LED technology has experienced from the color to color, from light to bright, low light efficiency to rise from the path of high light efficiency, and constantly improve the performance of LED to promote the deepening to various application fields. The content of LED and the growth of epitaxial chip technology and manufacturing sectors in the LED industry chain, equipment investment intensity, while profit margins are relatively high, is a capital intensive industry, the typical market position, the technology and development level of national LED industry structure and the company plays a decisive role.

In recent years, China's LED epitaxial chip industry with the rapid development of LED applications and the rapid development of. According to the national semiconductor lighting engineering research and development and Industry Alliance released statistics, from 2009 to 2011, the domestic LED epitaxial chip industry rose from $6 billion 500 million to $2 billion 300 million, an annual compound growth rate of 68.11%.

China's LED industry from the initial development package, the initial chip is mainly dependent on imports, in recent years, in and around the downstream demand pull policy under the support of the main LED epitaxial chip domestic enterprises to increase R & D investment, and actively develop the expansion plan, the market for the epitaxial chip link investment increase, the domestic LED epitaxial chip industry to accelerate the development of our country, to 2011 domestic chip rate has reached 70%. According to the statistics of alliance of national semiconductor lighting project, in 2009 China's LED epitaxial chip industry market size of about 2 billion 300 million yuan, to 2011 has risen to 6 billion 500 million yuan, the annual compound growth rate of 68.11%.

According to the alliance national semiconductor lighting project statistics, in 2010 the domestic LED chip demand equivalent to 2 inch wafer has reached 490 thousand / month, an increase of 48%, the forecast, the next five years the domestic display chip with LED demand will continue to maintain a steady growth trend, with the further improvement and application of back lighting light permeability start, the domestic LED epitaxial chip demand will significantly increase, to 2015, the domestic LED chip demand equivalent to 5 million 550 thousand pieces / month for 2 inch wafer, is about 11 times that of 2010.
