Abstract

A semiconductor device includes a semiconductor element having a semiconductor chip and connection terminals, a cooling fin to which the semiconductor element is fixed, and an external cooling body having a passage for cooling medium, the cooling fin being fixed to the external cooling body. The semiconductor element has a protruding cooling block that is inserted and fixed to the cooling fin, which in turn is fixed to the external cooling body such that the cooling fin is in contact with the cooling medium.
