摘要： An object is to provide a semiconductor device having a structure with which parasitic capacitance between wirings can be sufficiently reduced. An oxide insulating layer serving as a channel protective layer is formed over part of an oxide semiconductor layer overlapping with a gate electrode layer. In the same step as formation of the oxide insulating layer, an oxide insulating layer covering a peripheral portion of the oxide semiconductor layer is formed. The oxide insulating layer which covers the peripheral portion of the oxide semiconductor layer is provided to increase the distance between the gate electrode layer and a wiring layer formed above or in the periphery of the gate electrode layer, whereby parasitic capacitance is reduced.

摘要： To provide a semiconductor element in which generation of oxygen vacancies in an oxide semiconductor thin film can be suppressed. The semiconductor element has a structure in which, in a gate insulating film, the nitrogen content of regions which do not overlap with a gate electrode is higher than the nitrogen content of a region which overlaps with the gate electrode. A nitride film has an excellent property of preventing impurity diffusion; thus, with the structure, release of oxygen in the oxide semiconductor film, in particular, in the channel formation region, to the outside of the semiconductor element can be effectively suppressed.
