Abstract:
A process for forming a plastic carrier, comprising:forming a matrix of lead frames arranged in a 2-dimensional regular pattern out of a metal strip, each lead frame including a die-attach pad and a plurality of leads disposed in close proximity to said die-attach pad, said die-attach pad and said leads each having a bottom surface and a top surface;attaching to the top surface of each die-attach pad a semiconductor die, said semiconductor die having a plurality of bonding pads formed thereon;providing bond wires to electrically connect each of said bonding pads to the top surface of a corresponding lead; andencapsulating said matrix of lead frames, including said die-attach pads, said semiconductor dies, said bond wires and said leads, in a resin material such that said bottom surfaces of said die-attach pads and said bottom surfaces of said leads are exposed.
