Abstract

To improve the productivity of manufacturing semiconductor devices having a heat sink, the semiconductor device manufacturing method includes: (a) setting an integral heat radiation body set 30 of multiple heat radiation bodies 32 in a mold 40 cavity 42; (b) setting a substrate 10 on which multiple semiconductor chips 20 are mounted in a planar arrangement in the mold 40 so that the multiple semiconductor chips 20 are located inside the cavity 42; and (c) sealing the multiple semiconductor chips 20 and affixing the heat radiation body set 30 by filling the cavity 42 with a sealant.
