Appeal No. 1998-0096
Application No. 08/518,182
difference between Fujimoto and the claimed invention is that
Fujimoto does not disclose polymer composite bumps that have a
circular cross section prior to bonding together the substrate
and the integrated circuit element. Saito (JP4-6841) provides
for such a deficiency, disclosing that the composite bumps
have "a cylindrical shape, but this invention is not limited
by these examples. Any shapes including spherical shapes and
columnar shapes are, of course, applicable” (Translation, page
8). We agree with the examiner that Saito (JP4-6841) “teaches
that a columnar shaped body and a spherical (hence circular)
shaped cross section are equivalents. . .” (Answer, page 5).
We find it abundantly clear that the combined teachings of
Fujimoto and Saito (JP4-6841) would have suggested the
interchangeability of the columnar-shaped polymer body with
the cylindrical (or spherical)-shaped polymer body. Thus, the
combination of Fujimoto and Saito (JP4-6841) would have
suggested to one skill in the art the substitution of Saito’s
cylindrical (or spherical)-shaped polymer body for Fujimoto’s
columnar-shaped polymer body to arrive at the claimed
invention.
In addition, we have before us in claims 7, 11, 15 and 18
