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. - 6 -Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
