Appeal No. 1997-4442
Application 08/353,040
De Wit further discloses that substrate 12 may be a
semiconductor substrate or a semiconductor layer grown or
deposited on another semiconductor layer or on an insulating
layer (col. 2, lines 60-65). Appellants argue that de Wit
does not have an electrically insulating substrate (Br5), but
"suggests a semiconductor layer substrate formed on an
insulating layer" (RBr2 n.1). The distinction between an
insulating "layer" and an insulating "substrate" is not
addressed by the Examiner. However, we find that an
insulating layer on a substrate broadly constitutes an
insulating substrate.
Appellants argue that the materials of the first and
second resistors in de Wit do not contain metals, whereas
claim 6 recites that the resistance path has two alloy
portions (Br5). The Examiner acknowledges the argument but
does not answer it (EA5). De Wit does not disclose alloy
resistances. Although de Wit discloses that the concept is
applicable to any kind of resistor, it does not contain any
teaching of the construction of other kinds of resistors. The
anticipation rejection of claims 6 and 2 is reversed for this
reason.
