Abstract
PURPOSE:To dispense with the unnecessary area and to increase the degree of integration for the subject semiconductor device by a method wherein a source and drain region and a channel region are formed using a self-aligning method. CONSTITUTION:A semiconductor region 52, wherein P type impurities are selectively injected, is additionally formed on a P type substrate 1, and a field oxide film 53 is formed on the surface of the region 52. On the above film 53, a conductive film 54, whereon N type impurities are injected on the whole surface, and an insulating film 55 are formed. Then, an etching is selectively peformed on the expected region whereon a transistor channel of the first insulating film 54 will be formed, and another etching is performed on the surface of the semiconductor substrate using the remaining insulating film 55 as a mask. Then, the exposed surface of the semiconductor substrate is oxidized, a gate oxide film 56 is formed, a polycrystalline silicon is formed on the film 56, and a gate electrode 57 is formed. Besides, N type impurities are injected on the substrate surface from the conductive film 54 by performing a diffusion process, and an N<+> region 58 is formed. This region 58 is turned into the source and drain of the transistor.
