Patent ID: 8362511

Claim:
A semiconductor light emitting structure, comprising: a substrate having a luminous zone and a non-luminous zone; a second type electrode layer formed on the substrate, wherein a current spreading grating formed by a plurality of conductive pillars and a plurality of conductive walls, which are staggered and connected to each other, is formed within the luminous zone, and each conductive pillar and each conductive wall respectively have a first top surface and a second top surface parallel to the substrate; a reflecting layer and an insulating layer formed on the second type electrode layer in sequence, wherein the reflecting layer and the insulating layer cover the conductive pillars and the conductive walls, and the first and the second top surface are exposed; a first type electrode layer, a first type semiconductor layer, an active layer formed on the insulating layer located within the luminous zone in sequence; a second type semiconductor layer formed on the active layer, wherein the second type semiconductor layer covers the conductive pillars and the conductive walls; and a first contact pad formed on the first type electrode located within the non-luminous zone.
