Abstract:
1. A semiconductor device, comprising: a substrate; a conductive layer over the substrate; a first dielectric layer over the conductive layer, the dielectric layer having a first opening; a first plurality of conductive nanotubes over the dielectric layer; a second plurality of conductive nanotubes over the first opening in the dielectric layer; a second dielectric layer above the first plurality of conductive nanotubes and the second plurality of conductive nanotubes, the second dielectric layer having a second opening that is over the second plurality of conductive nanotubes; and a conductive material in the second opening to form electrical contact between the conductive layer and the conductive material through the second plurality of conductive nanotubes, wherein the first plurality of nanotubes extends from the first dielectric layer to the second dielectric layer and the second plurality of nanotubes extends from the conductive layer to the conductive material.
