Patent attributes
Disclosed herein is an apparatus for providing conductivity. The apparatus may include an epitaxial layered structure having a first-type doped semiconductor layer, a second-type doped semiconductor layer, and an active layer between the first-type doped semiconductor layer and the second-type doped semiconductor layer. The apparatus may also include a conductive layer adjacent to and in ohmic contact with the first-type doped semiconductor layer. The conductive layer may have a micropixellated structure comprising a plurality of micropixel contact areas that are electrically isolated from each other. The plurality of micropixel contact areas may be sized and spaced to allow multiple ones of the plurality of micropixel contact areas to overlap a single contact pad for providing charge flow for a pixel in an array of pixels formed using the epitaxial layered structure.
