Abstract:
1. A method for enhancing heat dissipation in a packaged integrated circuit comprising: attaching a semiconductor die with an electronic circuit to a heat spreader to create a thermal contact between the semiconductor die and the heat spreader; providing conductive terminals on a first surface and a second surface of an insulating substrate, such that selected conductive terminals on the first surface are in thermal contact with the heat spreader and connected by vias to selected conductive terminals of the second surface; and encapsulating the semiconduct of die and the heat spreader; providing external terminals that are adapted for coupling the selected conductive terminals on the second surface to conductors on a printed circuit board, thereby allowing heat generated in the electronic circuit to be dissipated from the semiconductor die, through the second semiconductor die, the selected conductive terminals of the insulating substrate and the external terminals to the printed circuit board.
