Abstract:
1. A high electron mobility transistor (HEMT) comprising: an insulation layer on a substrate; a gate electrode, a source electrode, and a drain electrode, on the insulation layer; a channel supply layer on the insulation layer, the channel supply layer contacting the gate electrode, the source electrode, and the drain electrode; and a channel layer on the channel supply layer, the channel layer including a two-dimensional electron gas (2DEG) induced by the channel supply layer, an effective channel region contacting the channel supply layer, and a high resistivity region on the effective channel region, the high resistivity region being a region in which impurities are ion-implanted, wherein the high resistivity region extends through a part of a top portion of the channel layer, and the part of the top portion of the channel layer including the high resistivity region corresponds to a region between the gate electrode and the drain electrode and does not correspond to a region between the gate electrode and the source electrode.
