Patent ID: 7977132

Claim:
A method for fabricating a light emitting diode (LED) structure, comprising: forming LED layers by epitaxially growing a first conductivity type layer over a growth wafer, a light-emitting layer over the first conductivity type layer, and a second conductivity type layer over the light-emitting layer; forming trenches along die edges to expose the first conductivity type layer at the die edges, the trenches reaching at least partially into the first conductivity type layer, the trenches forming mesa structures of LED dies; electrically insulating regions of the exposed first conductivity type layer at the die edges by forming electrically insulating regions at the die edges; and forming first conductivity type and second conductivity type bond pad layers over the LED dies, the first conductivity type and the second conductivity type bond pad layers extending over singulation streets between the LED dies, the first conductivity type and the second conductivity type bond pad lavers being electrically coupled to the first conductivity type and the second conductivity type layers, respectively.
