Patent ID: 7911234

Claim:
A device comprising: a substrate; a layer of carbon nanotubes on the substrate comprising a first plurality of carbon nanotubes that are generally parallel with respect to one another, and at least one carbon nanotube that is misaligned with respect to the first plurality of carbon nanotubes; a logic cell formed from a portion of the layer of carbon nanotubes and comprising: a plurality of cell nodes formed in or on the layer of carbon nanotubes and comprising a first input contact, a second input contact, an output contact, a first gate region, and a second gate region, such that: the output contact is positioned between the first input contact and the second input contact, and wherein a cell region is bounded by a width of the output contact and resides between the first input contact and the second input contact; the first gate region is positioned between the first input contact and the output contact; and the second gate region is positioned between the second input contact and the output contact, and wherein the first gate region and the second gate region are positioned to provide a logic function; and at least one nonconductive region in the layer of carbon nanotubes, and positioned within the cell region and between any two or more of the plurality of cell nodes that, if shorted, would inhibit the logic function.
