ABSTRACT:
A light-emitting device includes a compound substrate including a high thermal conductive layer and a substrate disposed around the high thermal conductive layer, an adhesive layer formed on the compound substrate, and a light-emitting stack layer formed on the adhesive layer. Therefore, problems in cutting a metal layer in a grain cutting process are solved.
