Title: Manufacture of semiconductor device
Inventor: KUROKI HIROKI
IPC: H01L21/318
Filed: 1991-11-05
Abstract: PURPOSE:To form an extremely thin SiO2/Si3N4 (stacked insulating film with good film thickness and electrical properties. CONSTITUTION:After forming an Si3N4 film, thermal nitriding is performed. Then, the Si3N4 film is oxidized and an SiO2 film is formed on the surface of the Si3N4 film. Since resistance to oxidation of the Si3N4 film is improved by performing the thermal nitriding, an extreme increase in the film thickness of insulating film does not occur due to the oxidation of the Si3N4 film to its lower part even if forming the SiO2 film without reducing the oxidation, thereby, obtaining the good film thickness. Further, since the oxidation is not reduced, the stacked insulating film with a little leakage current and good electrical properties can be obtained.
