ABSTRACT:
A light-emitting device comprises a channel structure in the semiconductor layer for connecting an electrode and an ohmic contact layer by means of a substrate transfer process including a wafer-bonding process and a substrate-lifting-off process. The channel structure is formed in the semiconductor stack for electrically connecting the ohmic contact layer and the electrode and driving the current into the light-emitting device. Thereby, a horizontal type or a vertical type of light-emitting device has a good ohmic contact and high light efficiency.
