Abstract
A metal film and a doped a-Si film are deposited on a glass substrate, and successively etched by photolithography using the same resist pattern, to form a metal electrode and doped a-Si layers. The doped a-Si layers thus formed are then re-etched to remove portions protruding from the metal electrode. Then, a non-doped a-Si layer and a transparent electrode are successively formed on the doped a-Si layer. A protection film may additionally be deposited on the glass substrate before the deposition of the metal film.
