Development of Industry First 6-inch GaN Substrates for use in White LEDs by Sumitomo Electric
Industry leader in production of 2-inch diameter GaN substrates for blue-violet laser for production of Blu-ray DVD player, Sumitomo Electric has announced the successful development of world’s first 6-inch diameter gallium nitride (GaN) based substrate for use in white Led applications. The new product will allow for better thermal dispersion, while helping the LED manufacturers in their quest for chip size reduction and increase output power.
The GaN has been chosen by the company as an alternative to sapphire. The front face of the newly developed substrate is a polarized c-plane. Sumitomo Electric is expecting the wide spread use of these materials in both white LEDs as well as power devices.
