Abstract:
It is an object to provide a highly reliable semiconductor device including a thin film transistor with stable electric characteristics. In a semiconductor device including an inverted staggered thin film transistor whose semiconductor layer is an oxide semiconductor layer, a buffer layer is provided over the oxide semiconductor layer. The buffer layer is in contact with a channel formation region of the semiconductor layer and source and drain electrode layers. A film of the buffer layer has resistance distribution. A region provided over the channel formation region of the semiconductor layer has lower electrical conductivity than the channel formation region of the semiconductor layer, and a region in contact with the source and drain electrode layers has higher electrical conductivity than the channel formation region of the semiconductor layer.

Claim (Index 1):
A semiconductor device comprising:\n a gate electrode layer over a substrate having an insulating surface; a gate insulating layer over the gate electrode layer; an oxide semiconductor layer including a channel formation region over the gate insulating layer; a buffer layer over the oxide semiconductor layer; and source and drain electrode layers over the buffer layer, wherein in the buffer layer, a first region which is in contact with the source and drain electrode layers has higher electrical conductivity than a second region which is in contact with the channel formation region of the oxide semiconductor layer.
