Patent ID: 7541216

Claim:
A method of forming a nanotube connection aligned to an etched feature, the method comprising: forming a raised feature on a substrate surface, the feature including a top surface and sides; forming a spacer on a side of the raised feature, the spacer being shorter than the raised feature so that the top portion of the raised feature extends above the top of the spacer and a portion of the side of the raised feature is exposed thereby defining a notched region above the spacer and adjacent to the top portion of the raised feature; depositing and patterning a nanotube layer on the substrate such that the nanotube layer is deposited in the notched region and contacts the exposed portion of the raised feature and overlaps a portion of the top of the raised feature; forming an insulating layer on the substrate that covers the nanotube layer; and removing a top portion of the insulating layer to expose a top portion of the etched feature and removing the nanotube layer from on top of the etched feature leaving a portion of the nanotube layer in contact with the etched feature.
