Abstract:
1. A light emitting diode chip, comprising: a semiconductor material capable of emitting light from a planar surface responsive to application of a potential across a first metallic wire bonding pad structure disposed on the planar surface and ohmicly coupled with an p-doped region of the semiconductor material, and a second metallic wire bonding pad structure ohmicly coupled with a n-doped region of the semiconductor material, and wherein at least the first metallic bonding pad structure is ohmicly coupled with the p-doped region of the semiconductor material by a current spreading layer disposed on the planar surface that contacts both the first metallic bonding pad structure and the p-doped region of the semiconductor material, and wherein the first metallic bonding pad structure is separated physically from the semiconductor material by a non-perforated layer of dielectric material disposed on the p-doped region of the semiconductor material.
