can be omitted. Schantz does not teach or suggest using his
resistors to effect bonding between the polymer tape and the
barrier layer or between the polymer tape and the silicon
substrate.
Takatsu discloses a method of cementing (i.e., bonding)
by melting thermoplastic surfaces together. Takatsu teaches
(translation, p. 3) that when cementing objects, the cemented
portion must have characteristics (physically and chemically)
identical to the materials of the subject to be cemented.
Takatsu also teaches (translation, p. 4) that a heating unit
is located in contact with or near the thermoplastic surfaces
to be cemented together (see the nichrome wires 5 in Figures
1(a), 1(b) and 2(a)).
In our view, the only suggestion for modifying Schantz in
the manner proposed by the examiner to meet the above-noted
limitation stems from hindsight knowledge derived from the
appellants' own disclosure. The use of such hindsight
knowledge to support an obviousness rejection under 35 U.S.C.
§ 103 is, of course, impermissible. See, for example, W. L.
