Abstract

A semiconductor device includes a single lead frame, a semiconductor element, and a mold material. The semiconductor element is joined onto one main surface of the lead frame. The lead frame includes a die-attach portion, a signal terminal portion, and a ground terminal portion. The die-attach portion, the signal terminal portion, and the ground terminal portion are disposed directly below the mold material so as to be arranged in a direction along one main surface. A groove portion is provided by partially removing the lead frame so as to allow the groove portion to pass therethrough, the groove portion being provided between the die-attach portion and the ground terminal portion adjacent to each other in the lead frame and between the signal terminal portion and the ground terminal portion adjacent to each other in the lead frame.
