Patent ID: 8736042

Claim:
A high power surface mounted semiconductor package comprising: a lead frame having: (i) a die attach pad having a die attachment surface and an elongate ground lead that extends in a first direction; (ii) a plurality of input/output (I/O) elongate leads arranged about the die attach pad, said leads also extending in said first direction; and (iii) an up-set bonding pad electrically connected with the die attach pad, the up-set bonding pad including a bonding support configured to support a plurality of wire bonds and arranged to include a large mold flow aperture between the die attachment site and the bonding support; a semiconductor integrated circuit die mounted on the die attachment surface of the die attachment pad; a set of wire bonds comprising at least one wire bond electrically connecting the die to at least one of: the bonding support of the up-set bonding pad; the elongate ground lead, and at least one of the I/0 leads; and a mold envelope encapsulating the package with a mold material, the envelope encapsulating the die; an upper portion of the attach pad; a portion of the ground lead; portions of the I/0 leads, the up-set bonding pad; and the set of wire bonds and wherein the mold materials fill the mold flow aperture to form a mold locking feature.
