Abstract:
A semiconductor device comprises a substrate; a conductive layer deposited on a substrate, the conductive layer being patterned to include a first pattern, the first pattern including a major surface and a plurality of grids defined in the major surface, the major surface including first lines and a connecting portion, wherein the connecting portion is connected to an electrode; and an epitaxial layer disposed on the conductive layer, covering the grids and the first line between the adjacent grids.
Abstract:
A method of forming a current diffusion layer is provided that comprises providing an epitaxial wafer. The method further comprises depositing ITO source material on the epitaxial wafer to form a base ITO layer by a direct current electron gun and depositing ZnO source material, during simultaneous deposition of the ITO source material, on the base ITO layer to form a ZnO doped ITO layer by a pulse current electron gun. The ZnO source material is deposited at a deposition rate higher than the rate at which the ITO source material is deposited. Generation and termination of current may be controlled by adjusting a duty cycle of pulse current provided by the pulse current electron gun and result in discontinuous deposition of the ZnO source material. The method further comprises depositing the ITO source material on the ZnO doped ITO layer to cover the ZnO doped ITO layer and form a finished ITO layer.
