Patent ID: 8481369

Claim:
A method for packaging a semiconductor die, the method comprising: attaching a first side of the die to a first side of a flag of a lead frame; taping a second side of the lead frame; electrically connecting bonding pads on a second side of the die opposite to the first side of the die to leads of the lead frame with wires; encapsulating at least the second side of the die, the wires, and the first side of the lead frame with a mold compound via a molding process, wherein the molding process includes placing the taped lead frame into a first part of a mold chase that has first protrusions on a surface thereof, said first protrusions arranged to project between the leads and the flag of the lead frame; and removing the tape from the second side of the lead frame, whereby a semiconductor package that is formed has indentations between the leads and the flag.
