Abstract
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.
