Abstract:
A lead frame for a semiconductor device, the lead frame having opposite first and second sides bounded respectively by first and second parallel reference planes between which a thickness is defined, the lead frame comprising:a support having a surface at the first side of the lead frame for receiving a semiconductor chip; and a plurality of leads spaced from the support to be electrically connected to a semiconductor chip on the support, a first lead in the plurality of leads having a length between first and second ends and a width taken transversely to the length, the first end of the first lead having a first region that has a thickness less than the thickness of the first lead at the second end of the first lead so that at least a part of the first region is offset from the second reference plane toward the first reference plane, the first end of the first lead having at least a first protrusion projecting away from the first reference plane.
