Abstract: An object is to provide a technique capable of improving heat dissipation while maintaining the workability of a product in a semiconductor device. A semiconductor device includes power chips, control chips configured to control the power chips, power side terminals, control side terminals, and a mold resin covering the power chips, the control chips, one ends side of the power side terminals, and one ends side of the control side terminals. An other ends side of the power side terminals and an other ends side of the control side terminals protrude horizontally from a side surface of the mold resin and bend downward at middle parts thereof. Of the power side terminals and the control side terminals, only on the other ends side of the power side terminals, heat dissipation portions protruding in a direction approaching or away from the mold resin from portions bent downward are formed.

Abstract: A semiconductor device includes: a first semiconductor integrated circuit including at least a first terminal and a second terminal; a first lead frame connected to the first terminal; a second lead frame connected to the second terminal; and a mold resin covering the first semiconductor integrated circuit. The mold resin further covers the first lead frame with a portion of the first lead frame being exposed. The mold resin further covers the second lead frame with a tip of the second lead frame opposite to the second terminal being exposed. The mold resin includes a recess, and the recess is opened to expose only the portion and the mold resin.
