Appeal No. 2002-1182 Application 09/233,385 Be all this as it may, however, both Pasch and Rostoker establish that the flip chip electronic module recited in claim 50 lacks novelty. Each of these references discloses a flip chip module composed of a semiconductor chip, a substrate, and a dielectric interposer having apertures, all as recited in claim 50. Each also discloses that the module is thermally reflowed such that the chip and substrate are electrically and mechanically interconnected by solder elements which are not in contact with an adjacent solder element as recited in claim 50. Although neither teaches that the solder elements are “cone shaped prior to thermal reflow” as recited in the claim,4 this limitation addresses the process by which the claimed thermally reflowed module is made and, on the record before us, does not distinguish the claimed module from that disclosed by either Pasch or Rostoker. In this regard, it is the patentability of the product claimed, and not of the recited process limitations, which must be established. See In re Hallman, 655 F.2d 212, 215, 210 USPQ 609, 611 (CCPA 1981); In re Brown, 459 F.2d 531, 535, 173 USPQ 685, 688 (CCPA 1972). The patentability of a claimed 4 The appellants’ specification indicates that “[t]he cone shape solder 637 permits a reduced force for a given I/O pad to allow for some non-planarity between the chip [i.e., the die], the interposer, and the substrate” (specification, page 11). 7Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
