ABSTRACT:
A method to assemble a non-leaded semiconductor package is disclosed. In one embodiment, a carrier tape is attached to a metal foil. A plurality of leadframes are formed in the metal foil, each leadframe including a die pad laterally surrounded by a plurality of contact leads. A semiconductor die, including an active surface with a plurality of die contact pads, is attached to each die attach pad and electrically connected to the leadframe by a plurality of bond wires connecting the die contact pads and the lead contact areas of the contact leads. A plurality of leadframes, each including a wire bonded semiconductor die, are encapsulated with mold material. The carrier tape is removed and the non-leaded semiconductor packages separated.
