Abstract

A single crystal silicon substrate which comprises an electric insulation member and a single crystal silicon film formed on the insulation member. The silicon film has first regions and second regions. Each of the first regions is formed as a strip shape and has a high density of inorganic impurities implanted thereinto. Each of the second regions is formed as a strip shape and has a low density of the impurities. The first and second regions are alternatively arranged contacting with each other so that the first regions are separated from each other.
