Patent ID: 8809898

Claim:
A semiconductor light-emitting device, comprising: a conductive support structure; a semiconductor structure over the conductive support structure, the semiconductor structure having a first surface, a second surface, and a side surface, wherein the semiconductor structure comprises a p-type layer, an active layer on the p-type layer, and an n-type layer on the active layer, wherein the second surface is opposite the first surface, and wherein the first surface, relative to the second surface, is proximate to the conductive support structure; a first metal electrically connected to the p-type layer, wherein the first metal is located between the conductive support structure and the first surface of the semiconductor structure; a passivation layer comprising a first portion on the second surface of the semiconductor structure and a second portion on the side surface of the semiconductor structure, wherein the first portion has a first surface contacting the second surface of the semiconductor structure and a second surface opposite the first surface of the first portion; and a second metal electrically connected to the n-type layer, wherein the second metal is located on the second surface of the semiconductor structure, wherein the second metal comprises a first part located higher than the second surface of the first portion, and wherein a contact area between the second metal and the semiconductor structure is greater than a contact area between the second metal and the passivation layer.
