Oxygen defects formed at the boundary between the zinc oxide type oxide semiconductor and the gate insulator are terminated by a surface treatment using sulfur or selenium as an oxygen group element or a compound thereof, the oxygen group element scarcely occurring physical property value change. Sulfur or selenium atoms effectively substitute oxygen defects to prevent occurrence of electron supplemental sites by merely applying a gas phase or liquid phase treatment to an oxide semiconductor or gate insulator with no remarkable change on the manufacturing process. As a result, this can attain the suppression of the threshold potential shift and the leak current in the characteristics of a thin film transistor.
