Method For Fabricating High-Efficiency Light Emitting Diode Having Light Emitting Window Electrode Structure

A lateral light emitting diode device includes: a substrate; an n-type GaN layer disposed on the substrate; an activation layer disposed on the n-type GaN layer; a p-type GaN layer disposed on the activation layer; a current spreading layer disposed on the p-type GaN layer; a p-electrode disposed on the current spreading layer; a MESA region formed by removing portions of the current spreading layer, the p-type GaN layer, the activation layer, and the n-type GaN layer; a transparent window layer disposed on the n-type GaN layer in the entire or part of the MESA region; a plurality of contact plugs which is in contact with the n-type GaN layer through the transparent window layer; and an n-electrode disposed on the transparent window layer to connect the plurality of contact plugs to each other.
