Appeal No. 2004-0999 Application No. 09/997,086 Examiner has not established a prima facie case of obviousness since the combination suggested by the Examiner does not teach or suggest "forming at least one wide trench through said microelectronic device wafer interconnect layer within said at least one dicing street" as required in independent claim 15. Therefore, we have not sustained the Examiner's rejection of claims 15, 19, and 20. Rejection of Claim 16 Dependent claim 16 is rejected under 35 U.S.C. § 103 as being obvious over Ibnabdeljalil in view of Igarashi and further in view of Kroeninger. We find that Kroeninger teaches laser cutting to form trenches as Examiner pointed out on page 8 of the answer. However, Kroeninger does not teach forming at least one trench through an interconnect layer. Consequently, the combination of Ibnabdeljalil, Mori, and Kroeninger does not teach or suggest "forming at least one wide trench through said microelectronic device wafer interconnect layer within said at least one dicing street" required in claim 16. Therefore, we will not sustain the rejection of claim 16. 15Page: Previous 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 NextLast modified: November 3, 2007
