1. A semiconductor device comprising:
- a substrate in which an internal wire is formed;
at least one semiconductor chip mounted on the substrate;
a heat spreader which is used for externally radiating heat from the semiconductor chip; and
a heat conductive material having flexibility, which is provided between the surface opposite to surfaces of the semiconductor chip near the substrate and the undersurface of the heat spreader in accordance with the height of the space therebetween, and has a plurality of bumps at least on the semiconductor chip side surface.

Abstract
A package is formed by mounting a plurality of semiconductor chips 6 and 7 on a substrate 1, arranging a heat spreader 13 on a resin surface opposite to a surface where pads 8 for the semiconductor chips are formed, via a curved intermediate plate 11 made of a metal, and filling with resin 14. The curved intermediate plate 11 is formed so as to easily bend in order to compensate the semiconductor chips 6 and 7 for the height difference relative to the heat spreader 13, and has a plurality of bumps 12 on the surface thereof in order to allow contact with the semiconductor chips by multipoint.
