Patent 7208826 was granted and assigned to Sanyo on April, 2007 by the United States Patent and Trademark Office.
Die pads 50, 51, an external connecting electrode 52 and a bridge are covered with an insulating resin after half-etching, formed into a single package without a coupling member such as a supporting lead or adhesive tape. In addition, since no supporting board is required, a low-profile semiconductor device with improved heat radiation can be provided.
