Abstract
This invention provides a light-emitting chip device with high thermal conductivity, which includes an epitaxial chip, an electrode disposed on a top surface of the epitaxial chip and a U-shaped electrode base cooperating with the electrode to provide electric energy to the epitaxial chip for generating light by electric-optical effect. The epitaxial chip includes a substrate and an epitaxial-layer structure with a roughening top surface and a roughening bottom surface for improving light extracted out of the epitaxial chip. A thermal conductive transparent reflective layer is formed between the substrate and the epitaxial-layer structure. The electrode base surrounds the substrate, the transparent reflective layer and a first cladding layer of the epitaxial-layer structure to facilitate the dissipation of the internal waste heat generated when the epitaxial chip emitting light. A method for manufacturing the chip device of the present invention is provided.
