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.
