Abstract:
In a semiconductor device including an oxide semiconductor, a change in electrical characteristics is inhibited and reliability is improved. The semiconductor device is manufactured by a method including first to fourth steps. The first step includes a step of forming an oxide semiconductor film, the second step includes a step of forming an oxide insulating film over the oxide semiconductor film, the third step includes a step of forming a protective film over the oxide insulating film, and the fourth step includes a step of adding oxygen to the oxide insulating film through the protective film. In the first step, the oxide semiconductor film is formed under a condition in which an oxygen vacancy is formed. The oxygen from the oxide insulating film fills the oxygen vacancy after the fourth step.

Claim (Index 10):
A manufacturing method of a semiconductor device comprising the steps of:\n forming an oxide semiconductor film with a sputtering apparatus; forming an oxide insulating film over and in contact with the oxide semiconductor film; forming a protective film over and in contact with the oxide insulating film; adding oxygen to the oxide insulating film through the protective film; removing the protective film; and forming an insulating film over and in contact with the oxide insulating film after removing the protective film, wherein the protective film comprises at least one element selected from In, Zn, Ga, Sn, Ti, Al, W, Ta, and Mo, and wherein the oxide semiconductor film is formed at a condition in which an oxygen partial pressure in the sputtering apparatus is higher than 0% and lower than 50%.
