ABSTRACT:
A method of encapsulating a semiconductor device permits use of the same mold for various package types. In one form, a mold (34 and 36) has a first cavity (50) in which a first insert (52 and 53) is positioned, the first insert defining a length and a width of a package body which is to be formed in the mold. The first insert in the first cavity also defines a second cavity (54) in which a second insert (56 and 57) is positioned, the second insert defining a thickness of the package body. Plastic is inserted into the mold to form the package body. To form other package types, one or more inserts are replaced instead of using a different mold. In another embodiment, the inserts are adjustable. For example, rather than having to change inserts to form a package with a different thickness, the inserts are adjusted by, for instance, a screw mechanism (66) within the mold or by the addition or removal of shims (60).
