Abstract

PURPOSE:To enhance the dielectric strength of an insulating film in a semiconductor device by performing the anodic oxidation of a semiconductor substrate on which the insulating film having a defective part is formed on the surface, thereby forming an oxide on the defective part. CONSTITUTION:When a defective part, e.g., a pinhole 3, a weak spot 4, a foregin material 5 or the like exists on an insulating film 2 formed on a semiconductor substrate 1, an anodic oxidation is performed, and an oxide with the substrate is reacted and produced at the refective part via a current flowing through the defective part in the insulation breakdown state. Thus, it can reasily form an insulating film having a necessary dielectric strength.
