following limitations: “directly on, and in physical contact
with, said sublayer: sections of high conductivity metal on said
sublayer; and coplanar sections of said diffusion barrier metal
interspersed between said sections of high conductivity metal.
. .” Similarly, independent claims 6 and 10 specify in pertinent
part the following limitations: “an overlayer of said diffusion
barrier metal on said conductive and said diffusion barrier metal
sections. . . .” Also similarly, independent claim 12 specifies
in pertinent part the following limitations: “an overlayer of
said first diffusion barrier metal on said sections of high
conductivity and said sections of said second diffusion barrier
metal. . . .” Further similarly, independent claim 13 specifies
in pertinent part the following limitations: “directly on, and in
physical contact with, said sublayer: sections of high
conductivity metal interspersed between said protruding sections.
. . .” Accordingly, independent claims 1, 3, 6, 10, 12, and 13
require inter alia a layer of diffusion barrier metal lying
under, lying over, or lying both under and over interspersed
