った。(2) Description of conventional technology Heat generated in conventional semiconductor integrated circuits (hereinafter referred to as chips)? Heat dissipation methods include a structure in which the substrate side of the chip, that is, the back surface, is brought into close contact with ceramic and heat is dissipated through heat conduction from this surface, or a structure in which the terminals on the front surface of the chip are connected to a similar base material and heat is dissipated from the back surface. In both cases, the only route for heat conduction was from the back of the chip, as the structure was such that heat was dissipated by attaching fins to the fins and conducting heat to the fins.
There is a drawback that the area of the heat dissipation fin needs to be increased due to limitations on the amount of heat generated by the chip or in accordance with the amount of heat generated.

供するものである。(4) Structure of the invention The non-invention is 1. Focusing on the fact that the surface area of a normal chip except for the terminal area is covered with an insulating protective film, there is a layer on the top of this film that is electrically unrelated to the circuit inside the chip. By creating a structure in which a thermally conductive metal film is provided, a heat conduction path is provided from one surface as well, whereas the structure conventionally relied on a heat conduction path only from the back surface.

像である。This structure has a metal spring inserted between the metal film on the chip surface and the cap according to the present invention. Conventionally, by making the chip unstructured, the heat of the chip was only conducted through the ceramic in contact with the back side of the chip, but by creating a path from the surface film to the cap through the hole, the heat dissipation effect has been improved.
