Abstract
Disclosed is a semiconductor device comprising an oxide semiconductor layer on a substrate and including a first part and a pair of second parts that are spaced apart from each other across the first part, a gate electrode on the first part of the oxide semiconductor layer, and a pair of electrodes on corresponding second parts of the oxide semiconductor layer. A first thickness of the first part of the oxide semiconductor layer is less than a second thickness of each second part of the oxide semiconductor layer. A number of oxygen vacancies in the first part of the oxide semiconductor layer is less than a number of oxygen vacancies in each second part of the oxide semiconductor layer.
