US Patent 7399691 - Aligning nanotubes for crossbar array

http://www.freepatentsonline.com/7399691.html

This is a continuation patent originating from Harvard based on technology used to fabricate the NRAM technology developed by Nantero. Claim 1 reads:

1. A method comprising:

aligning a plurality of nanoscopic wires using a mechanically patterned surface to define a set of aligned nanoscopic wires on the surface, wherein the mechanically patterned surface comprises a plurality of elongated trenches in the mechanically patterned surface, the elongated trenches each having a first dimension on the surface that is substantially longer than a second dimension on the surface, the second dimension being substantially greater than the greatest depth of the trenches; and

contacting the plurality of aligned nanoscopic wires on the surface with a common electrode.
