Abstract:
1. A power semiconductor module, comprising: a frame made of an insulator and having a bottom opening and a top opening; a first electrode plate made of a metal and fixed in the bottom opening in said frame; a semiconductor element having a front surface electrode and a reverse surface electrode, said reverse surface electrode being electrically and physically connected to a principal surface of said first electrode plate; a multilayer substrate comprising a circuit plate, an insulating plate, and a metal plate stacked together, said metal plate being fixed to the principal surface of said first electrode plate; a wiring member that electrically connects the front surface electrode of said semiconductor element to the circuit plate of said multilayer substrate; a second electrode plate made of a metal and fixed in the top opening in said frame; and a metal block that has a first surface having a protrusion and a second surface opposite thereto and that tapers from said first surface to said second surface, said protrusion being electrically and physically connected to the circuit plate of said multilayer substrate, and said second surface of the metal block being electrically and physically connected to said second electrode plate.
