Patent ID: 8216885

Claim:
A method of manufacturing a semiconductor package which contains a semiconductor die and a metallic leadframe, comprising: providing the leadframe having a mounting area for mounting the die and a plurality of cantilever leads with a first end oriented away from the mounting area and a second end oriented toward the mounting area, wherein the cantilever leads each has a first thickness at the first end and a second thickness at the second end to form a recessed surface at the second end, the first thickness being greater than the second thickness; disposing one or more non-conductive supports adjacent to the recessed surface of the cantilever leads to support the cantilever leads; electrically connecting a plurality of bond pads of the die to the cantilever leads at the second end, wherein the die is mounted in the mounting area; and encapsulating at least a portion of the die, the leadframe, and the supports with an encapsulant.
