Patent ID: 6867066

Claim:
A method for producing a semiconductor device, comprising the steps of: (a) producing a shallow metal basin having a flange outwardly extending from a top edge of a side wall of said shallow metal basin, said flange having a predetermined size and shape and having a flat top side, (b) adhering a semiconductor device chip having at least one semiconductor device element disposed therein and at least one bonding pad arranged therein on a bottom plate of said shallow metal basin, (c) producing an insulator frame having a flat first side and a second side with at least one bonding pad arranged thereon, said insulator frame having a shape corresponding approximately to the shape of said flange, (d) adhering said first side of said insulator frame to said top side of said flange of said shallow metal basin, so that said insulator frame and said shallow metal basin are entirely disposed on opposite sides of a plane defined by said top side of said flange and said first side of said insulator frame, (e) connecting said at least one bonding pad arranged on said semiconductor device chip and said at least one bonding pad arranged on said second side of said insulator frame with at least one bonding wire, each at least one bonding wire being wire bonded to a respective bonding pad at a bonding location that is disposed directly above part of said shallow metal basin, (f) joining at least one solder ball to said at least one bonding pad arranged on said second side of said insulator frame; and (g) covering said semiconductor device chip, said at least one bonding wire, and a part of said at least one bonding pad arranged on said second side of said insulator frame with a resin cover, employing a molding process, said resin cover having an outer peripheral edge that overlaps said part of said at least one bonding pad arranged on said second side of said insulator frame and that protrudes to a location closely adjacent a side of said at least one solder ball, wherein each at least one bonding pad has an enlarged portion with a predetermined width and an elongated portion that extends from the enlarged portion and that has a width which is substantially smaller than the width of the enlarged portion, wherein step (e) comprises connecting each said at least one wire to the elongated portion of a respective said at least one bonding pad, and wherein step (f) comprises joining each said at least one solder ball to the enlarged portion of a respective said at least one bonding pad.
