发明名称 Etching of substrates of light emitting devices
摘要 Fabrication of a light emitting device includes etching of a substrate of the light emitting device. The etch may be an aqueous etch sufficient to increase an amount of light extracted through the substrate. The etch may be a direct aqueous etch of a silicon carbide substrate. The etch may remove damage from the substrate that results from other processing of the substrate, such as damage from sawing the substrate. The etch may remove an amorphous region of silicon carbide in the substrate.
