Abstract
A semiconductor device is disclosed that includes a semiconductor element, a circuit board electrically connected to the semiconductor element, a heat dissipation member fixed to the first surface of the circuit board and thermally coupled to the semiconductor element, and an interposer provided to the second surface of the circuit board facing away from the heat dissipation member. The interposer is electrically connected to the circuit board. An opening is formed in the circuit board and the interposer so that the semiconductor element is thermally coupled directly to the heat dissipation member through the opening.
