Abstract:
A semiconductor device, comprising:a semiconductor substrate; a gate electrode in Schottky contact with a surface of the semiconductor substrate, the gate electrode extending in a first direction; a drain electrode disposed on one side of the gate electrode, spaced apart from the gate electrode by some distance, and in ohmic contact with the semiconductor substrate; and a source electrode formed on the surface of the semiconductor substrate, the source electrode including: a main part in ohmic contact with the semiconductor substrate in a region across the gate electrode from the drain electrode, a shielding part disposed between the gate and drain electrodes as viewed along a direction normal to the surface of the semiconductor substrate, the shielding part extending in the first direction, and an overhanging part passing over the gate electrode and connecting the shielding part with the main part, wherein the total dimension of the overhanging part along the first direction is smaller than a total dimension of the shielding part along the first direction.
