Abstract
A press pack power semiconductor device incorporates a number of semiconductor elements. The power semiconductor device has a first insulating frame surrounding each of the semiconductor elements and having a lattice for positioning the semiconductor elements. First and second hard metal electrode plates are provided on the respective sides of each semiconductor element. A first electrode member is in contact with the first hard metal electrode plate. A second insulating frame, having a lattice for positioning the second hard metal electrode plate, is laid on the first insulating frame. A second electrode member is provided. This second electrode member has a lattice-shaped groove in which a lattice-shaped frame portion of the second insulating frame is fitted for positioning.
