Abstract
A method for producing a capacitor which includes, as one electrode, an electrical conductor having formed on the surface thereof a dielectric layer and, as the other electrode, a semiconductor layer, the method including producing fine electrically defective portions in the dielectric layer and forming the semiconductor layer on the dielectric layer by electrification. The capacitor obtained by the method of the present invention has good capacitance appearance factor, low ESR and is excellent in reliability.
