Abstract
PURPOSE: To prevent oxidation of high melting point metal films, reduce the leads between electrode wiring metals and form high melting point metal gates of low resistance by forming an anti-oxidizing film through heat treatment then oxidizing a polycrystalline semiconductor film thereby providing a second insulation film.
CONSTITUTION: Oxide films 14 are selectively forme don the surface of a silicon substrate 13 of one conductivity type of a semiconductor substrate except the portions for forming electrodes. Next, the portions where the surface is exposed are oxidized to form gate oxide films 15 and further Mo films 16 of a high melting point metal are deposited. Next, source and drain regions 17a, 17b of conductivity type opposite from that of the substrate are formed, thence windows 18 are opened in the film 15 of the regions 17a, 17b, after which a polycrystalline Si film 19 is deposited. Thereafter, the film 19 is oxidized in a high temperature steam atmosphere to form a SiO2 film 19' and further a MoSi2 film 16' which becomes oxidation prevention is formed on the surface of the Mo film 16. Thereafter, contact windows 18' are opened in the film 19' and an Al film is evaporated, after which the Al film is selectively removed to form wirings 20.
