Appeal No. 1998-0096 Application No. 08/518,182 the art would not have substituted Tsukagoshi’s aluminum layer 9 of very fine particles 8 for Fujimoto’s bump conductive layer 25. Accordingly, we do not sustain the obviousness rejection of claim 25 based on the combination of Fujimoto and Tsukagoshi, or in the alternative based on the combination of Fujimoto, Saito (JP4-6841) and Tsukagoshi. The 35 U.S.C. § 103(a) Rejection of Claims 8, 13, 26 and 29 The 35 U.S.C. § 103(a) Rejection of Claim 8 Based on the Combination of Fujimoto and Saito (JP4-6841) In interpreting claim 8, it is our view that the composite bumps must be provided on the substrate pads before the step of bringing together the substrate and the integrated circuit element. We agree with the appellants’ argument that the "composite bumps are formed on the substrate before the bond is formed and not the integrated circuit element, as in Fujimoto and Saito (JP 4-6841)" (Brief, page 18). The differences between the device resulting from the applied prior art and the claimed invention still exist. As such, the examiner has failed to establish a prima facie case of obviousness. 29Page: Previous 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 NextLast modified: November 3, 2007
