Abstract:
1. A method of forming a semiconductor device over a substrate, comprising: forming a first conductive layer over the substrate; forming a first dielectric layer over the first conductive layer; forming a first opening in the first dielectric layer; depositing a seed layer over the first dielectric layer and in the first opening; forming a layer of conductive nanotubes from the seed layer over the first dielectric layer and over the first opening; forming a second dielectric over the layer of conductive nanotubes; forming a second opening in the second dielectric layer over the first opening; and depositing conductive material in the second opening, wherein a first portion of the conductive nanotubes extends from the first dielectric layer to the second dielectric layer and a second portion of the conductive nanotubes extends from the first conductive layer to the conductive material.
