Abstract:
1. A method for manufacturing an embedded metal heat sink for a semiconductor device, comprising: providing an adhesive tape, wherein the adhesive tape includes a first surface and a second surface on opposite sides, and the first surface of the adhesive tape is adhered to a surface of a temporary substrate; providing at least one semiconductor device, wherein the at least one semiconductor device includes a first side and a second side opposite to the first side, the first side of the at least one semiconductor device is pressed and set into a portion of the second surface of the adhesive tape to expose the second side of the semiconductor device, and the semiconductor device has two electrodes with different conductivity types; forming a thin metal layer on the second side of the at least one semiconductor device and the exposed portion of the second surface of the adhesive tape, wherein a portion of a surface of the thin metal layer contacts with the second side of the at least one semiconductor device; forming a metal heat sink on the thin metal layer; removing the adhesive tape and the temporary substrate to expose the at least one semiconductor device and the surface of the thin metal layer; and deposing a plurality of bonding pads on the exposed portion of the surface of the thin metal layer around the at least one semiconductor device, wherein the bonding pads are respectively corresponding to the electrodes of the at least one semiconductor device, and the electrodes are electrically connected to the corresponding bonding pads through at least two wires.
