Abstract

PURPOSE: To obtain an IGFET using a transition metal oxide film especially for a gate insulation film by penetrating the gate insulation film without performing light oxidation and by implanting ion.
CONSTITUTION: An SiO2 is provided on the surface of a p-type Si substrate 1 for implanting a channel of BF2. The SiO2 film is eliminated and a tantalum pentoxide 2 is sputtered. Treatment is performed within dry O2 at 800°C and an SiO2 film 3 is formed between the substrate 1 and the tantalum pentoxide 2. Then, a W film 4 is sputtered and a PSG 5 is superposed. The PSG 5 is subjected to patterning and the W film 4 is machined with the PSG 5 as a mask. Then, As ion is implanted, thermal treatment is performed within N2 for producing an n+ layer 6, and a drain layer is provided in self-aligned manner to a W gate pattern. Further, an interlayer insulation film 7 is superposed and a wiring metal film 8 is provided for completing an FET. With this method, it is possible to form an IGFET without performing light oxidation even if a material with an extremely rapid diffusion of an oxidation seed such as tantalum pentoxide is used as a gate insulation film.
