Claim:
1. A high electron mobility transistor (HEMT) comprising: a channel supply layer; a channel layer on the channel supply layer, a source electrode, a drain electrode, and a gate electrode spaced apart from each other and supporting the channel supply layer; a source contact pad connected to the source electrode; a drain contact pad connected to the drain electrode; a gate contact pad connected to the gate electrode; and a buffer layer on the channel layer, the first via hole and the second via hole each having widths that are less than respective widths of the two of the source electrode, the drain electrode, and the gate electrode, and less than respective widths of uppermost portions of the first one and the second one of the source contact pad, the drain contact pad, and the gate contact pad, and the channel supply layer is on a third one of the source contact pad, the drain contact pad, and the gate contact pad.
