A method for forming a conductive feature in a low k dielectric layer comprising
a layer of nanotubes and a low k material between the nanotubes is provided. The
low k dielectric layer may be deposited on a seed layer as a blanket layer that
is patterned such that a conductive feature may be formed in the low k dielectric
layer. Alternatively, the low k dielectric layer may be selectively deposited on
a patterned seed layer between a sacrificial layer of a substrate. The sacrificial
layer may be removed and replaced with conductive material to form a conductive
feature in the low k dielectric layer.
