Patent ID: 7595511

Claim:
A nitride micro LED (Light Emitting Diode) with high brightness, comprising: a plurality of micro-sized luminous pillars having an n-type GaN layer formed on a substrate, and active layer 3 formed on the n-type GaN layer, and a p-type GaN layer formed on the active layer; a gap filling material filled between the luminous pillars to have substantially the same height as the luminous pillars, wherein the gap filling material includes at least one selected from SiO 2 , Si 3 N 4 , or a combination thereof, polyamide, and ZrO 2 /SiO 2 or HfO 2 /SiO 2 , and wherein the gap filling material is formed to have substantially the same height as the luminous pillars through a CMP (Chemical Mechanical Polishing) process; a p-type transparent electrode formed on a top surface of the gap filling material and the luminous pillars; a p-type electrode formed on the p-type transparent electrode; an n-type electrode electrically connected to the n-type GaN layer, wherein an array of the luminous pillars is driven at the same time; and wherein a top surface of the p-type GaN layer of the luminous pillars has convex surfaces formed through the CMP process.
