GaN-on-Si Substrate Technology and Market for LED and Power Electronics

WEST HARTFORD, Conn., April 16, 2014 /PRNewswire-iReach/ -- Global Information Inc. announces the addition of a new market research report "GaN-on-Si Substrate Technology and Market for LED and Power Electronics" at

Today, GaN on Sapphire is the main stream technology for LED manufacturing. GaN-on-Si technology appeared naturally as an alternative to sapphire to reduce cost. Our cost simulation indicates that the differential in silicon substrate cost is not enough to justify the transition to GaN-on-Si technology. The main driver is the ability to manufacture in existing, depreciated CMOS fabs in 6" or 8".

Despite potential cost benefits for LEDs, the mass adoption of GaN-on-Si technology for LED applications remains unclear. Opinions regarding the chance of success for LED-on-Si vary widely in the LED industry from unconditional enthusiasm to unjustified skepticism. Virtually all major LED makers are researching GaN-on-Si LED, but few have made it the core of their strategy and technology roadmap. Among the proponents, only Lattice Power, Plessey and Toshiba have moved to production and are offering commercial LED-on-Si.

At Yole Développement, we believe that although significant improvements have been achieved, there are still some technology hurdles (performance, yields, CMOS compatibility). We consider that if the technology hurdles are cleared, GaN-on-Si LEDs will be adopted by some LED manufacturers, but will not become the industry standard. We expect that Silicon will capture less than 5% of LED manufacturing by 2020.
