There is provided a semiconductor device including: a lead frame including a first opening portion; a resin filled in the first opening portion; and a semiconductor element electrically connected to the lead frame, wherein a side wall surface of the lead frame in the first opening portion has a larger average surface roughness than an upper surface of the lead frame.

Semiconductor device, method of manufacturing semiconductor device, and module

Provided is a semiconductor device including a conductive member including a main surface facing one side in a thickness direction; a semiconductor element including a plurality of pads facing the main surface of the conductive member; and a plurality of electrodes protruding from the plurality of pads toward the other side in the thickness direction. The conductive member includes a plurality of recessed portions recessed from the main surface toward the other side in the thickness direction. The semiconductor device further includes a bonding layer that is conductive and that is arranged in each of the plurality of recessed portions. The plurality of electrodes are separately inserted into the plurality of recessed portions. The conductive member and the plurality of electrodes are bonded through the bonding layers.
