ABSTRACT:
A method for manufacturing a mask ROM by first forming a contact hole with a semiconductor within. A surface treatment is then applied to supply by hydrogen atoms to the surface of the semiconductor. The contact hole is selectively irradiated with energy beams so as to produce an irradiated contact hole and a non-irradiated contact hole. In the non-irradiated contact hole a conductive or semiconductor thin film is formed and a circuit formed on the conductive or semiconductor thin film. The circuit and the non-irradiated hole are connected to each other and the irradiated hole and the circuit are insulated from each other.
