A semiconductor package comprises a die attach pad and a support member at least partially circumscribing it. Several sets of contact pads are attached to the support member. The support member is able to be etched away thereby electrically isolating the contact pads. A method for making a leadframe and subsequently a semiconductor package comprises partially etching desired features into a copper substrate, and then through etching the substrate to form the support member and several sets of contact pads. Die attach, wirebonding and molding follow. The support member is etched away, electrically isolating the contact pads and leaving a groove in the bottom of the package. The groove is able to be filled with epoxy or mold compound.
