Patent ID: 11948868
Assignee: STMICROELECTRONICS S.R.L.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. A method, comprising:
coupling a semiconductor die to a die pad, the die pad having an inner portion and an outer portion, the inner portion being larger than the outer portion, wherein the inner portion includes a plurality of protrusions along a first side of the die pad, wherein the plurality of protrusions form recesses between adjacent protrusions;
electrically coupling the semiconductor die to a plurality of leads, the plurality of leads facing the first side of the die pad, the plurality of leads including upper portions and base portions, wherein the base portions of the plurality of leads are staggered relative to the plurality of protrusions of the inner portion of the die pad, wherein the upper portions form lead locks extending in a direction of adjacent leads; and
encapsulating the semiconductor die with encapsulation material,
wherein the upper portions of the plurality of leads extend beyond the base portions of the plurality of leads on opposing sides of the upper portions; and
wherein the base portions of the plurality of leads face the outer portion of the die pad and are aligned relative to the recesses between adjacent protrusions.
