Abstract:
To improve field-effect mobility and reliability of a transistor including an oxide semiconductor film. Provided is a semiconductor device including an oxide semiconductor film. The semiconductor device includes a first insulating film, the 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 oxide semiconductor film includes a first oxide semiconductor film, a second oxide semiconductor film over the first oxide semiconductor film, and a third oxide semiconductor film over the second oxide semiconductor film. The first to third oxide semiconductor films contain the same element. The second oxide semiconductor film includes a region where the crystallinity is lower than the crystallinity of one or both of the first oxide semiconductor film and the third oxide semiconductor film.

Claim (Index 10):
A manufacturing method of a semiconductor device, comprising the steps of:\n forming a first oxide semiconductor film comprising indium, gallium, and zinc over a substrate with a first oxygen flow rate ratio; and forming a second oxide semiconductor film comprising indium, gallium, and zinc over and in contact with the first oxide semiconductor film with a second oxygen flow rate ratio higher than the first oxygen flow rate ratio.
