ABSTRACT:
In a semiconductor device module of this invention, on a metal base is formed a metal layer, on which an insulating substrate is formed. On the insulating substrate is formed conducting film patterns, to which a power device and a control device for controlling the power device are electrically connected. The metal layer exists only between the insulating substrate and the base under the power device, whereas a space is provided between the insulating substrate and the base under the control device, and is filled with air.
