Abstract
The disclosure illustrates a composite substrate and a method for manufacturing the same, the method including: disposing a mask layer on an upper surface of a substrate; forming a plurality of mask patterns spaced apart from each other to form a plurality of intervals thereamong; filling a dummy metallic material into the intervals; removing the mask patterns to form a mesh-like dummy metallic layer; and removing the dummy metallic layer while depositing a nitride layer so as to form a mesh-like structure confined by the nitride layer and the substrate. The disclosure also illustrates a method for manufacturing a light-emitting device using the composite substrate.
