Abstract:
A semiconductor package comprising:a lead frame including a plurality of conductive contacts, wherein at least some of the conductive contacts have a top surface, a top facing shelf and a bottom surface; a die having top and bottom die surfaces, the die including a plurality of bond pads disposed on the top die surface and a metallic layer disposed on the bottom die surface, and wherein the bottom surfaces of the conductive contacts are substantially co-planar with the bottom die surface; connectors for electrically connecting selected bond pads to associated contacts, wherein the connectors are attached to the top facing shelves of the contacts; and a casing formed over the top die surface and the shelf portions of the contacts thereby encapsulating the connectors while leaving the bottom surfaces of the contacts and die exposed at a bottom surface of the package, wherein material that forms the casing is also exposed on the bottom surface of the package substantially co-planer with the bottom surfaces of the contacts to isolate the contacts.
