    摘要: The semiconductor device of this invention includes an active region formed from a group III nitride semiconductor grown on a substrate and an insulating oxide film formed in a peripheral portion of the active region by oxidizing the group III nitride semiconductor. On the active region, a gate electrode in Schottky contact with the active region extending onto the insulating oxide film and having an extended portion on the insulating oxide film is formed, and ohmic electrodes respectively serving as a source electrode and a drain electrode are formed with space from side edges along the gate length direction of the gate electrode.

    摘要: A semiconductor device includes an AlGaN film formed on a GaN film on a substrate, a gate electrode formed on the AlGaN film, and source and drain electrodes formed on either side of the gate electrode on the AlGaN film. An n-type InxGayAl1-x-yN film is interposed between the source and drain electrodes and the AlGaN film. Alternatively, the semiconductor device includes an n-type InxGayAl1-x-yN film formed on a GaN film on a substrate, a gate electrode formed on the InxGayAl1-x-yN film, and source and drain electrodes formed on either side of the gate electrode on the InxGayAl1-x-yN film.
