The migration of circuit fabrication technology from the microscale to the nanoscale has generated a great deal of interest in how the fundamental physical limitations of materials will change the way we engineer computer systems. The changing relationships between performance, defects, and cost have motivated research into so-called disruptive or exotic technologies. Chris Dwyer, from Duke University will present the theory, design, and methods of fabrication for DNA self-assembled nanostructures within the context of circuit fabrication.  The advantages of this technology go beyond the simple scaling of device feature sizes (sub-20nm) to enable new modes of computation that are impractical under the constraints of conventional fabrication methods.
