Patent ID: 7737455

Claim:
An electrode structure, the electrode structure comprising: a semiconductor material having a cutout formed therein, the semiconductor material defining a portion of an LED; an electrically insulating dielectric material; and a metal electrode; wherein a portion of the electrode is formed outside of the cutout and a portion of the same electrode is formed inside of the cutout; wherein the portion of the electrode outside the cutout is separated from the semiconductor material by the dielectric material; wherein the portion of the electrode inside the cutout is in electrical contact with the semiconductor material and wherein the dielectric material is optically transmissive, having an index of refraction greater than or equal to one and less than that of a semiconductor upon which the dielectric material is formed, and having a thickness greater than ½λ, where λ is a wavelength of light generated by the LED; the dielectric material being formed to the electrode so as to enhance reflection of light.
