ABSTRACT:
A logic cell that is immune to misaligned carbon nanotubes. Carbon nanotubes are positioned on a substrate. Contacts are formed on a layer of carbon nanotubes, including a first input contact, a second input contact, an output contact, a first gate region, and a second gate region. The output contact is positioned between the first input contact and the second input contact, and a cell region is provided bounded by a width of the output contact and residing between the first input contact and the second input contact. A nonconductive region is positioned in the layer of carbon nanotubes between any two or more of the plurality of contacts that, if shorted, would inhibit a logic function.
