A semiconductor device having improved heat-dissipating characteristics employs a thin insulator film made of diamond, which has excellent thermal conductivity, as an insulator film which is formed on a chip immediately below a heat-dissipating bump electrode. Since the thin diamond film has excellent insulating properties and high thermal conductivity, it is possible to improve heat-dissipating characteristics of even a high-power semiconductor device such as a multichip module. In the case of, particularly, a multichip module, the insulation between a mother chip and a child chip can also be ensured by the presence of the thin diamond film.
