Document Type and Number:
Japanese Patent JPWO2022153806
Kind Code:
A1
Abstract:
A semiconductor device includes leads each having an obverse surface facing in a thickness direction and extending in a first direction crossing the thickness direction, a semiconductor element including electrodes connected to the obverse surfaces of the leads, and a sealing resin covering the leads and semiconductor element. The sealing resin includes a resin bottom surface opposite from the semiconductor element with respect to the leads in the thickness direction. The leads are mutually separated in a second direction orthogonal to the thickness direction and the first direction. Each lead includes a first reverse surface, a second reverse surface and a recessed surface facing away from the obverse surface in the thickness direction. The first and the second reverse surfaces are mutually separated with the recessed surface intervening in the first direction and exposed at the resin bottom surface. The recessed surface is covered with the sealing resin.
