Compound semiconductors are finding use in a wide range of applications, including Light Emitting Diodes (LEDs) for displays, microwave devices for mobile telephones and Laser Diodes (LDs)/Photo Detectors (PDs) for optical communications. Sumitomo Electric is the world's leading manufacturer of gallium arsenide (GaAs), indium phosphide (InP) substrates and the related epitaxial wafers like InGaAs or AlGaAs structures, which are key materials for such applications. State-of-the-art material gallium nitride (GaN) substrate has been recently added to our product line-up.
