Power module and fabrication method for the same
A power module includes: an insulating layer; a leadframe (metal layer) disposed on the insulating layer; a semiconductor chip disposed on the leadframe; and a mold resin formed so as to cover the semiconductor chip, at least a part of the metal layer, and at least a part of the insulating layer, wherein the insulating layer includes a relatively-soft insulating layer disposed at a side of the leadframe and a relatively-hard insulating layer disposed at an opposite side of the leadframes. Accordingly, there can be provided the power module with improved cooling capability and improved reliability, and the fabrication method for such a power module.
