Patent ID: 7030474

Claim:
A package for an integrated circuit die comprising: a die pad having a first die pad surface, a second die pad surface which is opposite the first die pad surface, and a peripheral die pad side surface which extends between the first and second die pad surfaces; a plurality of contacts, each of the contacts having a first end which includes a first end surface, a second end which is opposite the first end and includes a second end surface, a first contact surface, a second contact surface which is opposite the first contact surface, and opposing contact side surfaces which extend between the first and second ends and the first and second contact surfaces; an integrated circuit die disposed on the first die pad surface; at least one conductor electrically connected to and extending between the die and the first contact surface of a respective one of the contacts; a package body formed of an encapsulant material which covers the die, wherein at least portions of the second contact surface and the second end surface of each of the contacts are exposed in the package body; and a bump disposed on at least a portion of the second contact surface of each of the contacts for connecting the package to an underlying substrate; the die pad side surface including a means for vertically locking the die pad to the package body, and at least the first end surface of each of the contacts including a means for vertically locking the contacts to the package body.
