Abstract:
The field-effect mobility and reliability of a transistor including an oxide semiconductor film are improved. Provided is a semiconductor device including an oxide semiconductor film. The semiconductor device includes a first insulating film, an oxide semiconductor film over the first insulating film, a second insulating film and a third insulating film over the oxide semiconductor film, and a gate electrode over the second insulating film. The second insulating film comprises a silicon oxynitride film. When excess oxygen is added to the second insulating film by oxygen plasma treatment, oxygen can be efficiently supplied to the oxide semiconductor film.

Claim (Index 15):
A manufacturing method of a semiconductor device comprising the steps of:\n forming a first oxide semiconductor film over a substrate; forming a gate insulating layer comprising silicon, oxygen, and nitrogen over the first oxide semiconductor film using a plasma CVD apparatus; performing oxygen plasma treatment after forming the gate insulating layer using the plasma CVD apparatus; and forming a gate electrode on the gate insulating layer after performing the oxygen plasma treatment.
