Deterministic Nanowire Fanout and Interconnect Without any Critical Translational Alignment

S Sangeetha Vanathi

Abstract


Interfacing the nanoworld with the microworld rep- resents a critical challenge to fully integrated nanosystems. Solu- tions to this problem have generally required either nanoprecision alignment or stochastic assembly. A design is presented that allows complete and deterministic fanout of regular arrays of wires from the nano- to the microworld without the need for any critical trans- lational alignment steps. For example, deterministically connecting 10-nm wires directly to 3- m wires would require a translational alignment to within only about 6 m. The design also allows for nanowire interconnect and is independent of the technology used to fabricate the nanowires, enabling technologies for which align- ment remains very challenging. The impact of potential fabrication errors is analyzed and a structure is fabricated that demonstrates the feasibility of such a design.
