Abstract
A method of manufacturing a semiconductor device includes adhering together a heat dissipating body and a plurality of heat generating bodies via a thermally conductive sheet, by applying pressure to the heat dissipating body and the plurality of heat generating bodies in a thickness direction of the thermally conductive sheet with the thermally conductive sheet disposed therebetween, the thermally conductive sheet having a compression modulus of 1.40 MPa or less under a compressive stress of 0.10 MPa at 150° C.
