Abstract:
1. A semiconductor device comprising: a semiconductor substrate; a channel layer provided on one surface of the semiconductor substrate; a drain electrode formed on the channel layer; a source electrode formed on the channel layer at a portion apart from the drain electrode; a surface passivation film formed on the channel layer so as to cover the channel layer except for portions on which drain electrode and the source electrode are formed; a gate electrode disposed between the drain electrode and the source electrode so as to penetrate the surface passivation film to provide a Schottky contact to the channel layer; a connecting plate having a horizontally extending bridge structure extending from said gate electrode; and a field plate electrode protruding vertically downwards from the connection plate towards the surface passivation film, a bottom surface of the protruding field plate electrode being in contact with the surface passivation film, the field plate electrode located between the drain electrode and the gate electrode at a predetermined distance from the gate electrode, wherein the connecting plate electrically connects the gate electrode to the field plate electrode.
