ABSTRACT:
In a power module having at least one power device chip and circuits for driving and controlling the power device chip which are incorporated within one and the same package, a heat spreader which is constituted by a material having a heat dissipation property and supports the power device chip on its upper surface is inserted into an opening formed in a control substrate having an upper surface on which patterns for forming the chip driving and controlling circuits and a connection pattern for connection with the power device chip are printed, and the control substrate and the heat spreader inserted into the opening are fixedly supported on a base substrate. Thus, the power device chip and the control substrate can be disposed in plane and reduced in size.
