Abstract: A method for forming a semiconductor device comprises the steps of providing a semiconductor die having a plurality of pads thereon with at least one bond wire electrically coupled with one of the pads and providing a holder having a cavity therein. The die is placed in the cavity, then a layer of encapsulation is formed within the cavity to cover the die. Subsequently, the encapsulated die is removed from the cavity.

Abstract: A method of forming a semiconductor memory device comprises the steps of providing a semiconductor die, forming a temporary protective material over a surface of the die, and attaching the die to a first lead frame portion. Next, a protective material is contacted with a second lead frame portion and, subsequently, the second lead frame portion is electrically connected with the second lead frame portion with bond pads on the first surface of the die with bond wires. Subsequent to electrically connecting the die and the second lead frame portion the protective material is removed.

Abstract: A semiconductor die includes a metal layer deposited thereon for enhancing adhesion between the die and a mold compound package. The metal layer is substantially oxide free. The die is coated with a layer or layers of copper (Cu) and/or palladium (Pd) by electroplating or electroless coating techniques. The metal layer provides a uniform wetting surface for better adhesion of the die with the mold compound during encapsulation. The increased adhesion reduces delamination potential of the die from the package.

Abstract: A carrier for testing an unpackaged semiconductor die is provided. The carrier comprises a base for holding the die, an interconnect for establishing a temporary electrical connection with the die, and a force applying mechanism for biasing the die and interconnect together. The base includes external contacts arranged as flat metal pads in a dense grid array and electrically connected to a pattern of contact pads. The carrier also includes a pair of slide connector members which provide an electrical path between the contact pads on the base and corresponding contact pads on the interconnect. The slide connector members can be formed of molded plastic or ceramic and include tine contacts that slidably engage the contact pads on the interconnect and base. The slide connector members permit the interconnect to be easily replaced for testing of different types of dice.
