Abstract

A nitride semiconductor device includes: a first nitride semiconductor layer; a second nitride semiconductor layer formed on the first nitride semiconductor layer and having a wider band gap than the first nitride semiconductor layer; and a third nitride semiconductor layer formed on the second nitride semiconductor layer. A region of the third nitride semiconductor layer located below the gate electrode is formed with a control region having a p-type conductivity, and a region of the third nitride semiconductor layer located between the gate electrode and each of the source electrode and the drain electrode is formed with a high resistive region having a higher resistance than the that of the control region.
