Abstract
A high-voltage field effect transistor a heterojunction is disposed between the first and second semiconductor material. A first composite passivation layer includes a first insulation layer and a first passivation layer, and a second composite passivation layer includes a second insulation layer and a second passivation layer. The first insulation layer is disposed between the first passivation layer and the second passivation layer, and the second passivation layer is disposed between the first insulation layer and the second insulation layer. A gate dielectric disposed between the second semiconductor material and the first passivation layer. A gate electrode is disposed above the gate dielectric. A first gate field plate is disposed between the first passivation layer and the second passivation layer. A source electrode and a drain electrode are coupled to the second semiconductor material.
