or suggests etching the metal layer to form a "knife-edge"
configuration thereon. Accordingly, the rejection of claim 12
under 35 U.S.C.
§ 103 is reversed.
Claims 29 and 30 respectively recite that the opening has
a conformal coating of a metal seed layer and the metal seed
layer is selected from a particular group of metals. We agree
with appellants that neither DiStefano alone nor DiStefano
considered with Ahmad teaches or suggests a conformal coating
on the opening in the metal layer of a metal seed layer let
alone a metal seed layer selected from particular metals.
Accordingly, we reverse the examiner's rejection of claims 29
and 30 under 35 U.S.C.
§ 103.
SUMMARY

examiner's rejection of claims 3, 4, 12, 29 and 30 under 35
U.S.C. § 103.
