Abstract
The light-emitting device includes a base plate, a bonding metal layer, a conductive oxide layer, an epitaxial layer, an insulation layer, a first ohmic contact layer, a second ohmic contact layer, a third ohmic contact layer, and a conductor line. The light-emitting device of the present invention uses the process of providing a conductor line to connect an ohmic contact layer, instead of wire bonding, so that a package process required by wire bonding can be eliminated to thereby reduce the size of the light-emitting device. Further, the light-emitting device, after the formation of the conductor line on the ohmic contact layer, allows for performance of a step of directly bonding to a circuit board so as to reduce the package size and simplify equipment necessary for the package process to thereby further lower down fabrication costs, achieving the effects of simplification of operation and fast fabrication.
