Abstract:
1. A method for fabricating a phosphor n-GaN up light-emitting diode (LED) wafer, comprising: providing a carrier substrate; depositing an n-GaN layer above the carrier substrate; depositing active layers above the n-GaN portion; depositing a p-GaN layer above the active layers; depositing one or more metal layers; applying a masking layer; etching the metal, the p-GaN layer, the active layers, and the n-GaN layer; removing the masking layer; depositing a passivation layer; removing a portion of the passivation layer on top of the p-GaN layer to expose the metal, depositing one or more layers; depositing a metal substrate; removing the carrier substrate to expose the n-GaN surface; and applying a phosphor layer above the n-GaN surface.
