Abstract
In a semiconductor device including a transistor, an oxygen release type oxide insulating film is formed in contact with a channel formation region of the transistor. The channel formation region is formed in an oxide semiconductor film. Oxygen is supplied from the oxide insulating film to the oxide semiconductor film. Further, an oxygen bather film which penetrates the oxide insulating film is formed around the channel formation region, whereby a diffusion of oxygen to the wiring, the electrode, and the like connected to the transistor can be suppressed.
