Researchers at OSRAM Opto Semiconductors have succeeded in manufacturing highperformance prototypes of blue and white LEDs, in which the light-emitting gallium-nitride layers are grown on silicon wafers with a diameter of 150 millimeters. The silicon replaces the sapphire commonly used until now without a loss in quality. Already in the pilot stage, the new LED chips are to be tested under practical conditions, meaning that the first LEDs on silicon from OSRAM Opto Semiconductors could hit the market in just two years.
