A method for manufacturing a field-effect transistor includes the steps of forming a source electrode and a drain electrode each containing hydrogen or deuterium; forming an oxide semiconductor layer in which the electrical resistance is decreased if hydrogen or deuterium is added; and, causing hydrogen or deuterium to diffuse from the source electrode and the drain electrode to the oxide semiconductor layer.

Field-effect transistor and method for manufacturing the same

A sheet material identifying device for identifying the kind of sheet material by applying vibration on the sheet material. The identifying device has a vibrator for applying vibration on the sheet material, a vibration sensor for detecting, via the sheet material, vibration applied by the vibrator, a device for changing a vibrating state between the vibrator and the vibration sensor, and an identifying section for identifying the kind of sheet material based on a detection result of the vibration sensor. Also, an image forming apparatus making use of the sheet material identifying device and a method of identifying the kind of sheet material are provided.
