Appeal No. 2004-0633 Application No. 10/011,198 alleged conflicts that appellants discuss, are relevant. We therefore are not persuaded by appellants’ arguments in this regard. Furthermore, we observe that Ito’s multilayer structure is used for making a “semiconductor device”. See column 1, lines 6-10 of Ito. Appellants have not directed us to evidence that the multilayer structure of Ito is not suitable for making the memory device. In view of the above, we therefore affirm the 35 U.S.C. § 103 rejection of claims 31, 32, and 33. III. The 35 U.S.C. § 103 rejection of claims 34, 35, and 36 as being obvious of Cronin in view of Ito and Yu Appellants discuss this rejection on pages 9-11 of the brief. Here, appellants allege that there are conflicts between Cronin, Ito and Yu. We refer to the above-discussed rejection with regard to our determinations with regard to appellants’ comments on the combination of Ito and Yu. We also provide the following. With regard to Cronin, appellants argue that Cronin forms a stud-down with a single edge through thick insulation and with a single metal deposition, whereas Yu proposes building up the contact level by requiring a plurality of thin insulating layers in a plurality of conductive fill steps for those holes. Brief, page 10. Appellants state that Cronin touts the benefits of a damascene process and that this conflicts with Yu because Yu utilizes a non-damascene process. Brief, pages 10-11. In view of the above, appellants present the same type of argument as presented with regard to the combination of Ito and Yu. Hence, for the very same reasons, discussed, supra, we are unpersuaded. 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
