Abstract

PURPOSE:To unnecessitate a special mask in a semiconductor device by forming a guard ring region in a self-alignment manner with selective oxidation technique. CONSTITUTION:A dioxidized silicon film 2, a nitrided silicon film 3 and a dioxidized silicon film 4 are sequentially covered on the front surface of a substrate 1, and are pattern etched by a photo resist film 5. Then, the film 5 is removed, it is thermally oxidized, and a field dioxidized silicon film 6 is formed. Then, the nitrided silicon film 3 is etched, is annealed in oxidative atmosphere, and a P<+> type region 7 forming a guard ring is formed. Thereafter, the film 3 is etched and removed, and an electrode 8 is formed.
