Abstract: Embodiments of the present invention relate to an improved package for a bi-directional and reverse blocking battery switch. According to one embodiment, two switches are oriented side-by-side, rather than end-to-end, in a die package. This configuration reduces the total switch resistance for a given die area, often reducing the resistance enough to avoid the use of backmetal in order to meet resistance specifications. Elimination of backmetal reduces the overall cost of the die package and removes the potential failure modes associated with the manufacture of backmetal. Embodiments of the present invention may also allow for more pin connections and an increased pin pitch. This results in redundant connections for higher current connections, thereby reducing electrical and thermal resistance and minimizing the costs of manufacture or implementation of the die package.

Abstract: Embodiments of the present invention relate to the use of stamping to form features on a lead frame of a semiconductor device package. In one embodiment, portions of the lead frame such as pins are moved out of the horizontal plane of a diepad by stamping. In certain embodiments, indentations or a complex cross-sectional profile, such as chamfered, may be imparted to portions of the pins and/or diepad by stamping. The complexity offered by such a stamped cross-sectional profile serves to enhance mechanical interlocking of the lead frame within the plastic molding of the package body. Other techniques such as selective electroplating and/or formation of a brown oxide guard band to limit spreading of adhesive material during die attach, may be employed alone or in combination to facilitate fabrication of a package having such stamped features.
