Abstract:
1. A method of manufacturing a semiconductor device comprising the steps of: forming a first insulating film comprising silicon oxide over a substrate in a multi-chamber apparatus having a plurality of film formation chambers; forming a semiconductor film comprising amorphous silicon on said first insulating film in said multi-chamber apparatus; forming a second insulating film comprising silicon oxide on said semiconductor film in said multi-chamber apparatus wherein said first insulating film, said semiconductor film and said second insulating film are successively formed without taking said substrate out of said multi-chamber apparatus; taking said substrate out of the multi-chamber apparatus after the formation of said second insulating film; crystallizing said semiconductor film outside said multi-chamber apparatus; patterning the crystallized semiconductor film to form a semiconductor island; and forming a gate insulating film on said semiconductor island, wherein said first and second insulating films are formed by plasma CVD using a raw material gas comprising TEOS.
