Patent ID: 7061026

Claim:
A light emitting diode, comprising: a transparent insulating substrate; a first conductivity type GaN as a first lower cladding layer directly over said transparent insulating substrate; an InGaN light-emitting layer directly over said lower cladding layer; a second conductivity type GaN as second upper cladding layer directly over said InGaN light-emitting layer; a GaN based contact layer with Gallium rich phase and thickness is between 5 Angstroms to 1000 Angstroms directly over said upper cladding layer; an AlGaInSnO system transparent conducting oxide (TCO) as a light transmitting layer directly over said GaN based contact layer, and the thickness of this TCO thin film must over 5 Angstroms; a first electrode formed on the partially exposed area of the first conductivity type GaN; and a second electrode formed on top of the light transmitting layer.
