Abstract:
A light emitting device includes a p-type semiconductor layer, an n-type semiconductor layer and an active region between the p-type semiconductor layer and the n-type semiconductor layer. A bond pad is provided on one of the p-type semiconductor layer or the n-type semiconductor layer, opposite the active region, the bond pad being electrically connected to the one of the p-type semiconductor layer or the n-type semiconductor layer. A conductive finger extends from and is electrically connected to the bond pad. A reduced conductivity region is provided in the light emitting device that is aligned with the conductive finger. A reflector may also be provided between the bond pad and the reduced conductivity region. A reduced conductivity region may also be provided in the light emitting device that is not aligned with the bond pad.
