Abstract:
A semiconductor device module, comprising:a plurality of semiconductor devices, each comprising: a semiconductor element having first and second surfaces, electrode terminals on said first surface, pads connected to respective electrode terminals and extending therefrom, insulated from said semiconductor element including said first surface thereof, and curved, flexible wires having first ends fixed to said pads and remote second ends; a heat spreader having a recessed inner wall and a peripheral edge engaged with said mounting board in such a manner that said second surfaces of the semiconductor elements face a bottom interior surface of the recessed inner wall; a thermal conductive resin layer of a substantially constant thickness disposed between each of said second surfaces of the semiconductor elements and said bottom interior surface of the recessed inner wall of the heat spreader and defining a uniform spacing of the respective second surfaces of the semiconductor elements from said bottom interior surface of the recessed inner wall of the heat spreader, the wires extending from the first surfaces of the respective semiconductor elements by distances which may vary randomly; a mounting board having plural terminals thereon respectively corresponding to the flexible wires and aligned with the remote second ends of the respective wires; and the peripheral edge of the heat spreader being affixed to a corresponding portion of the mounting board and spacing the recessed inner wall thereof at a distance from the mounting board such that wires extending by greater distances flex so as to permit wires extending by shorter distances commonly to engage and be connected to the respective terminals on said mounting board.
