InGaAIN light-emitting device and manufacturing method thereof

摘要

There is provided an InGaAlN light-emitting device and a manufacturing method thereof. The light emitting device includes a conductive substrate having a main surface and a back surface, a metal bonding layer formed on the main surface of the substrate, a light reflecting layer formed on the bonding layer, a semiconductor multilayer structure including at least a p-type and an n-type InGaAlN layer disposed on the reflecting layer, the p-type InGaAlN layer directly contacting the reflecting layer, and ohmic electrodes disposed on said n-type InGaAlN layer and on the back surface of the conductive substrate, respectively.
