Patent ID: 7906787

Claim:
A nitride micro LED with high brightness which is mounted through a flip-chip method, comprising: a sapphire substrate; a plurality of micro-sized luminous pillars having an n-type GaN layer grown on the sapphire substrate, an active layer 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 metal electrode formed on a top surface of the gap filling material and the luminous pillars; a p-type electrode formed on the metal electrode; and 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.
