Patent ID: 7598530

Claim:
A light emitting diode comprising: a first semiconductor structure comprising: a double hetero-structure comprising an n-type AlGaInP cladding layer, a p-type AlGaInP cladding layer, and an AlGaInP active layer sandwiched between the n-type AlGaInP cladding layer and the p-type AlGaInP cladding layer; a transparent conducting layer formed on and in ohmic contact with the n-type AlGaInP cladding layer; a first electrical contact in contact with the transparent conducting layer; a plurality of ohmic electrodes in ohmic contact with the p-type AlGaInP cladding layer; and a reflecting layer formed on an opposite side of the p-type AlGaInP cladding layer to the AlGaInP active layer; a second semiconductor structure comprising: a carrier substrate; an ohmic contact layer formed on the carrier substrate; and a second electrical contact formed on an opposite side of the carrier substrate to the ohmic contact layer; and an adhesive layer sandwiched between the reflecting layer of the first semiconductor structure and the ohmic contact layer of the second semiconductor structure.
