SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING SAME

摘要

Provided is a semiconductor device that includes: a gate electrode (2); a channel layer (7) that is disposed in a region directly below or directly above the gate electrode (2); a source electrode (5) and drain electrode (6), which are disposed in contact with the channel layer (7); and a first insulating layer (3) that is disposed between the gate electrode (2) and the channel layer (7). The channel layer (7) includes a first oxide semiconductor, the source electrode (5) and/or drain electrode (6) includes a second oxide semiconductor, and the first oxide semiconductor and the second oxide semiconductor contain indium, tungsten, and zinc. A method for manufacturing the semiconductor device is also provided.
