Patent ID: 6962836

Claim:
A method of manufacturing a resin-sealing type semiconductor device, comprising the steps of: preparing a multi-link lead frame formed by linking a plurality of package areas in a line, each of the package areas including a plurality of inner leads and a thin sheet-shaped insulating member joined to an end portion of each of said inner leads and capable of supporting a semiconductor chip; thereafter mounting a semiconductor chip on said insulating member in each of said package areas on which said inner leads and said insulating member are joined; connecting surface electrodes of said semiconductor chips and said inner leads corresponding thereto by respective wires; forming a seal portion by resin-sealing said semiconductor chips, said wires, and said insulating members; and separating a plurality of outer leads exposed from said seal portion, from a frame section of said lead frame; wherein said mounting step is performed such that a length of a shorter side of a main surface of said semiconductor chip formed in a quadrilateral shape is twice or less than twice a distance from a tip of the inner leads arranged at the farthest location from a center line of the semiconductor chip in a plane direction, to said semiconductor chip.
