Patent ID: 7579688

Claim:
A heat radiation structure of a semiconductor device, comprising: a substrate having, on a surface thereof, a first area on which the semiconductor device is mounted, and a second area which surrounds the first area; and the semiconductor device having a first surface and a second surface opposite to the first surface, the second surface having a periphery, the semiconductor device additionally having a plurality of terminals provided on the first surface, wherein the semiconductor device is mounted on the substrate in such a manner that the first surface is opposite to the surface of the substrate, wherein a first heat radiating film is disposed on the second area of the substrate, and a second heat radiating film is disposed on the second surface of the semiconductor device but does not extend beyond the periphery of the second surface, with the second heat radiating film being spaced apart from the first heat radiating film; wherein the first and second heat radiating films are independent of each other and are disposed at different distances from the substrate; and wherein the second heat radiating film has a peripheral edge and a rear side that are exposed to air.
