Abstract
A semiconductor device includes a first terminal, a second terminal, a first chip, and a resistance part. The first chip includes a substrate electrically connected to the second terminal, a nitride semiconductor layer located on the substrate, a first drain electrode located on the nitride semiconductor layer and electrically connected to the first terminal, a first source electrode located on the nitride semiconductor layer and electrically connected to the second terminal, and a substrate capacitance between the first drain electrode and the substrate. The resistance part is connected in series in a path including the substrate capacitance between the first drain electrode and the second terminal.
