Abstract:
1. A semiconductor device comprising: a thermally radiative and electrically conductive support plate, a regulatory semiconducting element and a passive semiconducting element both supported on one main surface of support plate, and an insulator adhered between said support plate and regulatory semiconducting element or between said regulatory semiconducting element and passive semiconducting element, said insulator having an insulative layer and an adiabatic layer bonded on said insulative layer under pressure, said insulative layer being adhered on said support plate or passive semiconducting element, said adiabatic layer being formed of a dielectric film containing gas bubbles or of foamed or expandable plastics interposed between said insulative layer and regulatory semiconducting element, and said insulative layer having its gas-bubble content less than that of said adiabatic layer, wherein said insulator is formed by fusing under pressure said adiabatic layer in the form of a corrugated resinous film on said insulative layer in the form of an adhesive plastic tape.
