Abstract: PURPOSE:To enable contact layers to be provided in proximity of a gate electrode and to decrease the size of source and drain regions substantially, by covering the whole surface with a polycrystalline silicon film and then selectively oxidizing the polysilicon film except the parts thereof located on the source and drain regions for forming the contact layers. CONSTITUTION:A gate electrode 3 of polycrystalline silicon is formed on the surface of a semiconductor substrate 1 through a gate insulation film 2. The gate electrode 3 is covered with a silicon nitride film 19. Then, the whole surface is covered with a first polysilicon film 13, which is further covered with an oxidation-resistant mask layer 14 of silicon nitride. The first polysilicon film 13 is selectively oxidized with the silicon nitride film 14 used as a mask, so that the parts of the first polysilicon film 13 located on source and drain regions 11, 12 are left as contact layers 15 while the other parts of the film 13 are convered into interlayer silicon oxide films 16. In this manner, apertures on the source and drain regions 11, 12 can be located in proximity of the gate electrode through side wall films 10 and the size of the source and drain regions can be reduced substantially. Accordingly, the semiconductor device is allowed to have a microminiaturized structure.
