US Patent 7989797 - Connectible nanotube circuit

http://www.freepatentsonline.com/7989797.html

This latest patent from Intellectual Ventures teaches a modified approach to the nanotube crossbar fabrics developed by Nantero for programmable logic in which a resist is placed between nanotube wires and selectively removed to program interconnections. Claim 1 reads:

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

a plurality of CNTs comprising:

a first selected CNT;

a second selected CNT arranged at a selected angle to the first selected CNT; and a removable intermediate layer interposed between the first selected CNT and the second selected CNT, the removable intermediate layer including at least one of a resist composition or a resist material, the at least one of a resist composition or a resist material configured for localized removal, characterized in that the first selected CNT and the second selected CNT are selected to form a junction having a selected electrical property when placed in contact at the selected angle.
