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 1):
A manufacturing method of a semiconductor device, comprising the steps of:\n forming a first insulating film over a substrate; forming an oxide semiconductor film over the first insulating film; forming a second insulating film over the oxide semiconductor film; forming a third insulating film over the oxide semiconductor film; and forming a gate electrode over the second insulating film, wherein the step of forming the oxide semiconductor film comprises the steps of:\n forming a first oxide semiconductor film; \n forming a second oxide semiconductor film over the first oxide semiconductor film; and \n forming a third oxide semiconductor film over the second oxide semiconductor film, \n wherein the first oxide semiconductor film, the second oxide semiconductor film, and the third oxide semiconductor film are successively formed with a sputtering apparatus in vacuum.
