Abstract
The invention of the present application provides a heat radiation structure of a semiconductor device, and includes 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. The semiconductor device has a first surface and a second surface opposite to the first surfaces, and is formed with a plurality of terminals provided on the first surface. The semiconductor device is mounted on the substrate in such a manner that the first surface is opposite to the surface of the substrate. A first heat radiating film is formed on the second area of the substrate, and a second heat radiating film is formed on the second surface of the semiconductor device, with the second heat radiating film being spaced apart from the first heat radiating film.
