US Patent 7932543 - Zigzag nanowire crossbar

Nanowire crossbar arrays can be more sensitive to stress during manufacture due to small wire diameters which leads to broken or damaged wires. This patent from Samsung teaches a nanowire array using a zigzag arrangement to avoid this problem. Claim 1 reads:

1. A wire structure including at least one first wire, wherein the at least one first wire comprises:

a first region having a width of several to tens of nanometers; and

a second region disposed at both ends of the first region and having a width wider than that of the first region,

wherein the second region is configured to prevent the first region from at least one of bending and breaking due to a stress, the wire structure includes a plurality of first wires in parallel, and ends on one side of the plurality of the first wires are offset from one another and are in a zigzag pattern.
