Abstract
A semiconductor layer () is provided on a substrate (). A gate electrode (), a source electrode () and a drain electrode () are provided on the semiconductor layer (). A first passivation film () covers the gate electrode () and the semiconductor layer (). A source field plate () is provided on the first passivation film (), and extends from the source electrode () to a space between the gate electrode () and the drain electrode (). A second passivation film () covers the first passivation film () and the source field plate (). The first passivation film () has a quasi-conductive thin film () provided at least between the gate electrode () and the drain electrode () and having an electric resistivity of 1.0 Ωcm to 10Ωcm.
