Abstract
A semiconductor device having a supporting member that reduces a resonance phenomenon. A pair of reinforcing members is fixed on a gate drive substrate with spacers interposed there between and upright portions of the pair of reinforcing members are fastened with screws on a side wall of a cathode flange. A spacer is fixed on the gate drive substrate and a projection of the spacer is inserted in an engaging member fixed on the bottom of the cathode fin electrode and thus fixed on the bottom of the cathode fin electrode. The pair of upright portions as the first and second supporting points and the projection of the spacer as the third supporting point stably support the gate drive substrate on the cathode fin electrode without freedom of rotation at the three positions arranged to surround an opening.
