Abstract:
1. A semiconductor device comprising: a substrate region; a gate electrode, a source electrode and a drain electrode which are placed on a first surface of the substrate region; an active area between gate and source placed between the gate electrode and the source electrode, the active area between gate and source placed along long-side directions of the gate electrode and the source electrode; an active area between gate and drain placed between the gate electrode and the drain electrode, the active area between gate and drain placed along long-side directions of the gate electrode and the drain electrode; an active area placed on the substrate region of an underneath part of the gate electrode, the source electrode, and the drain electrode; and a non-active area placed adjoining the active area, the active area between gate and source, and the active area between gate and drain, wherein a largest width along the long-side directions of the gate electrode and the source electrode of the active area between gate and source is wider than a largest width along the long-side directions of the gate electrode and the drain electrode of the active area between gate and drain, wherein the largest width along the long-side directions of the gate electrode and the source electrode of the active area between gate and source is respectively equal to a width along the long-side direction of the source electrode, a width along the long-side direction of the gate electrode, and a width along the long-side direction of the drain electrode.
