Title: Manufacture of semiconductor device
Inventor: GOCHO TETSUO
IPC: H01L21/28
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of characteristics and yield, when a compound film of semiconductor and metal is formed in sufficient thickness on the surface of a source/drain diffusion layer and on the upper surface of a gate electrode. SOLUTION: In this manufacturing method, heat treatment is performed in the state that the upper surface of a polycrystalline Si film 48 is covered with an Si3 N4 film 55, the Si3 N4 film 55 is eliminated, and a metal film is formed. An SiO2 film is hardly formed on the upper surface of the polycrystalline Si film 48 even if heat treatment is performed, and the Si3 N4 film 55 can be eliminated for a time shorter than the eliminating time of the SiO2 film. Thereby, when the Si3 N4 film 55 and the SiO2 film on the polycrystalline Si film 48 are perfectly eliminated, film thinning of SiO2 films 42, 65 can be restrained, and a leakage current between an n<+> diffusion layer 68 and a P well 45, and short-circuit between the n<+> diffusion layer 68 and the polycrystalline Si film 48 can be prevented.
