LED substrate material 3 scope covers sapphire, silicon carbide, silicon, however, because of sapphire technology is relatively mature, and many global manufacturers have long sapphire crystal production performance, so the mainland enterprises in the development of the LED with the base board, also with the sapphire material is given priority to, from 2010 to 2011, many existing companies, and new entrants announced plans to expand the sapphire investment.
LED with substrate technology development direction, the main column in the 12th five-year plan, 863 plan "efficient key materials, semiconductor lighting technology research and development" subsidy project, one of the subsidies if scan the plan content, can be found that the scope, including sapphire, silicon carbide, silicon material three areas, can be seen in the 12th five-year plan, China LED with substrate will develop toward diversification.
Of the 863 plan, the sapphire substrate development main lock sapphire substrate etching, production technology, and epitaxial scope of key raw materials, etc; Silicon substrate, with growth of 4 inches (including) above the blue and green light of epitaxial technology, large size and high power silicon substrate type LED grain production and packaging technology is given priority to; Silicon carbide substrate technology, in addition to the long jing, processing technology, also by using silicon carbide substrate development high white LED luminous efficiency of epitaxial, grain technology as the goal.
Although the mainland in the 12th five-year plan, LED substrate material 3 scope covers sapphire, silicon carbide, silicon, but because of sapphire technology is relatively mature, and many global manufacturers have long sapphire crystal production performance, so the mainland enterprises in the development of the LED with the base board, also with the sapphire material is given priority to, from 2010 to 2011, many existing companies, and new entrants announced plans to expand the sapphire investment.
