Semiconductor device

Abstract

Abstract PURPOSE:To achieve an effective cooling of a semiconductor element by constructing the inside wall of a device opposing to a semiconductor element making a smooth inclination toward the circumference from the top of the semiconductor, which is regarded as an apex. CONSTITUTION:The wall 21 opposing to a semiconductor element 26 has an apex on the upper section of the semiconductor element 26 and it is making a smooth inclination toward the circumference. The heat generated at the element 26 evaporates a refrigerant 27 toward the direction of an arrow 29. This evaporated refrigerant comes in contact with a wall 21 and adhered to the wall 21 as a liquefied refrigerant before evaporation. In such way, the refrigerant which is liquefied by contacting the wall 21 does not drop on the surface of the element 26 and the fine metal wire 22. Accordingly, the element 26 can be cooled without giving a bad influence to the semiconductor device.
