摘要： The semiconductor conductor device includes a gate electrode 106, an oxide semiconductor film 110, a source electrode 114a and a drain electrode 114b, and a channel region formed in the oxide semiconductor film. The channel region is formed between a first side surface 214a of the source electrode and a second side surface 214b of the drain electrode opposite to the first side surface 214a. The oxide semiconductor film has a side surface which overlaps with the gate electrode, which has a first high resistance region positioned between a first region 206a that is the nearest to one end 314a of the first side surface 214a and a second region 206b that is the nearest to one end 314b of the second side surface 214b.
