Abstract

A packaged semiconductor device that is fabricated with a plurality of conductive leads defined in a strip that beneficially includes a radio frequency shield box. The conductive contacts are located in a housing, beneficially by insert molding or by sandwiching between a bottom piece and a top piece. The housing can further include a cavity that receives a semiconductor device, and the radio frequency shield can receive another semiconductor device. Bonding conductors electrically connect at least one semiconductor device to another semiconductor device and/or to the conductive contacts. A conductive cover is disposed over the housing. The cavity beneficially includes a beveled wall and the conductive leads and the radio frequency shield are beneficially comprised of copper.
