Osram Opto Semiconductors is keeping pace with the constant growth of the market and switching its fabrication of red, orange and yellow light emitting diodes to 6-inch wafers. The German high-tech company is therefore extending the fabrication of all large-wafer LEDs to the indium-gallium-aluminum-phosphide (InGaAlP) material system and therefore expanding its production capacity. The company began switching fabrication of blue LED chips back in 2011.
