Abstract
A semiconductor device includes source electrodes having source fingers, drain electrodes having drain fingers, and gate electrodes having bent portions between steps formed in stepwise side portions of source fingers and steps formed in stepwise side portions of drain fingers and being bent in the bent portions along the source fingers and the drain fingers. A shape of the stepwise side portion of one source finger and that of the stepwise portion of the corresponding drain finger are symmetrical about a midpoint of an imaginary line that connects the other end of the source finger and the other end of the corresponding drain finger.
