Patent ID: 7667236

Claim:
A light emitting device including a semiconductor die, the semiconductor die comprising: an epitaxial structure arranged on a substrate, the epitaxial structure forming an active light generating region between a first layer on a first side of the active region and having a first conductivity type and a resistivity of less than twenty ohms per square, and a second layer on a second side of the active region and having a second conductivity type, the second side of the active region being opposite the first side of the active region and the second conductivity type being different that the first conductivity type; a first contact in operative electrical communication with the active region via the first layer in the epitaxial structure, the first contact being arranged on a side of the epitaxial structure opposite the substrate; a second contact in operative electrical communication with the active region via the second layer in the epitaxial structure, the second contact being arranged on a side of the epitaxial structure opposite the substrate; a first contact trace corresponding to the first contact and defined at a surface thereof distal from the substrate, the first trace including at least one area designated for bonding; and, a second contact trace corresponding the second contact and defined at a surface thereof distal from the substrate, the second trace including at least one area designated for bonding; wherein the first contact trace is substantially enclosed within the second contact trace.
