Patent ID: 8053795

Claim:
A light emitting device, comprising: a device structure comprising a first semiconductor layer, an active layer and a second semiconductor layer, wherein the device structure has inclined sidewalls; a first electrode formed over the second semiconductor layer; a passivation layer covering the inclined sidewalls and at least a portion of the first electrode; a second electrode contacting a surface of the device structure; a first metal layer formed on the first electrode wherein the passivation layer is arranged on the first metal layer; a reflective metal film interposed between the first electrode and the first metal layer, wherein each of the reflective metal and the first electrode has the same area without a significant difference; a second metal layer supporting the first semiconductor layer, the active layer and the second semiconductor layer, the first electrode and the first metal layer, wherein a portion of the first metal layer extends to at least the surface of the device structure; and Wherein each inclination angle of the sidewalls is substantially in the range of 45 to 65 degrees.
