US Patent 7696505 - CNT crossbar electronics

http://www.freepatentsonline.com/7696505.html

This patent is from Searete LLC (the patenting arm of Intellectual Ventures) teaches a carbon nanotube crossbar electronic systems similar to some of the designs developed by Nantero but with the inclusion of an intermediate resist layer that may be selectively removed to program the interconnects between nanotubes. Claim 1 reads:

1. A carbon nanotube (CNT) circuit template, comprising:

a first array of substantially parallel, laterally separated CNTs;

a second array of substantially parallel, laterally separated CNTs arranged at an angle to the first array; and

an intermediate layer interposed between the first array of CNTs and the second array of CNTs.
