Title: Manufacture of semiconductor device
Inventor: ICHIJO MITSUHIRO
IPC: H01L21/3065
Filed: 1997-03-22
Abstract: PROBLEM TO BE SOLVED: To improve the state of an interface between an active layer and a gate electrode of a thin film transistor. SOLUTION: After a pattern 104 of an active layer is formed, a processing with argon plasma is applied. Thereafter, a gate insulating film 107 is formed without permitting it to come into contact with fresh air. Hereby, a natural oxide film formed on the surface of the active layer is removed, and an adverse effect of the natural oxide film on the characteristics of a thin film transistor is restricted. This is effective for the case where a large number of TFTs are integrated on a substrate. This restricts variations of the characteristics of a large number of TFTs and a change with the passage of time of the same.
