Abstract:
1. A semiconductor device comprising: source electrodes that are provided on a semiconductor substrate and are having source fingers, the source fingers having stepwise side portions so that a length of the source fingers in a gate length direction decreases stepwise in a direction from ends of the source fingers connected to source pads towards other ends; drain electrodes that are provided on the semiconductor substrate and are having drain fingers, the drain fingers having stepwise side portions so that a length of the drain fingers in the gate length direction decreases stepwise in a direction from ends of the drain fingers connected to drain pads towards other ends, the stepwise side portions of the drain fingers corresponding to those of the source fingers; and gate electrodes that are provided on the semiconductor substrate and have bent portions between steps formed in the stepwise side portions of the source fingers and steps formed in the stepwise side portions of the drain fingers, the gate electrodes being bent in the bent portions along the source fingers and the drain fingers, a shape of the stepwise side portion of one of the source fingers and that of the stepwise portion of a corresponding one of the drain fingers being symmetrical about a midpoint of an imaginary line, that connects the other end of the one of the source fingers and the other end of the corresponding one of the drain fingers.
