Abstract:
An AlGaInP semiconductor light-emitting diode (LED) assembly comprising:a substrate; a first input terminal electrically coupled to said substrate; a plurality of layers formed on said substrate to form a light-emitting structure; a window structure formed on said light-emitting structure; and a second input terminal; wherein said window structure comprises: a first layer comprised of a first p doped semiconductor material other than AlGaInP; a second layer formed on said first layer and comprised of a second p doped semiconductor material other than AlGaInP and different from said p doped semiconductor material of said first layer; a third layer formed on said second layer and comprised of an amorphous conductive material; and an insulator formed on said first layer in a void etched in said second layer; wherein said second input terminal comprises a metal contact which passes through an opening in said third layer to said insulator; and forms an ohmic connection with said third layer.
