Abstract
A high electron mobility transistor having a channel layer, electron supply layer, source electrode, and drain electrode is included so as to have a cap layer formed on the electron supply layer between the source and drain electrodes and having an inclined side surface, an insulating film having an opening portion on the upper surface of the cap layer and covering the side surface thereof, and a gate electrode is formed in the opening portion and extending, via the insulating film, over the side surface of the cap layer on the drain electrode side. The gate electrode having an overhang on the drain electrode side can reduce the peak electric field.
