Abstract: The present invention provides a transistor structure with high field effect mobility. Since an oxide semiconductor layer through which carriers flow does not come into contact with the gate insulating film, the oxide semiconductor layer through which the carriers flow is set to have a buried channel structure that is separated from the gate insulating film. Specifically, an oxide semiconductor layer having high conductivity is provided between two oxide semiconductor layers. In addition, an impurity element is added to the oxide semiconductor layer in self-alignment to reduce the resistance of a region in contact with the electrode layer. Further, the thickness of the oxide semiconductor layer in contact with an insulating film is made thicker than that of the oxide semiconductor layer having high conductivity.
