Abstract:
1. A method of fabricating a semiconductor device comprising: providing a semiconductor wafer having a first surface and a second surface opposite of the first surface, the first surface having a plurality of circuit elements each of which is defined by scribe lines formed in the semiconductor wafer; forming a sealing resin on the first surface of the semiconductor wafer; forming a plurality of external terminals on the first surface of the semiconductor wafer, the external terminals respectively electrically connect to the circuit elements and project from the sealing resin; adhering the first surface of the semiconductor wafer to a supporter; separating the semiconductor wafer at the scribe lines, to divide the semiconductor wafer into a plurality of chips, each of the chips including a top surface corresponding to the first surface of the semiconductor wafer, a bottom surface corresponding to the second surface of the semiconductor wafer, and side surfaces between the top and bottom surfaces; and spraying a heat spreading material on the chips after said separating, to coat the bottom surfaces and side surfaces of the chips with the heat spreading material, wherein the chips remain adhered to the supporter during said spraying.
