  • Patent number: 7224049
    Abstract: A method of fabricating a lead frame for a semiconductor device having a semiconductor chip resin-sealed therein. The lead frame includes a lead to be electrically connected to the semiconductor chip within sealing resin and to be sealed into the sealing resin such that at least a part of its mounting surface is exposed from the sealing resin. The method includes a lead forming step for forming the lead, and a side edge coining step for subjecting a side edge of a sealed surface, which is a surface on the opposite side of the mounting surface, of the lead to coining processing from the side of the sealed surface, to form a slipping preventing portion. The slipping preventing portion is to project sideward from the lead and to have a slipping preventing surface between the mounting surface and the sealed surface of the lead.

  • Patent number: 7075173
    Abstract: Two dice may be provided within a single package so that one pin and associated leadfinger may be coupled to bond pads on different dice. This may mean that two different bond pads on different dice are coupled, for example by wirebonding, to the same leadfinger. An adhesive tape may be secured so as to bridge the two dice. One or more conductive traces are formed on the upper side of the adhesive tape and adhesive is provided on the other side to secure the tape to the two dice. As a result, wire bonds may be made from a pad on one die to a trace and then from the opposite side of the trace to a leadfinger. At the same time, a wire bond may be made from a pad on the other die to the same leadfinger. In another embodiment, an adhesive tape with a conductive trace on it may be used as a wire bond bridge to join spaced bond pads on a single chip.

  • Publication number: 20060099740
    Abstract: An apparatus and method for attaching a semiconductor die to a lead frame wherein the electric contact points of the semiconductor die are relocated to the periphery of the semiconductor die through a plurality of conductive traces. A plurality of leads extends from the lead frame over the conductive traces proximate the semiconductor die periphery and directly attaches to and makes electrical contact with the conductive traces in a LOC arrangement. Alternately, a connector may contact a portion of the conductive trace to make contact therewith.
