None
- *Background
- One of the most significant barriers to widespread commercialization ofnano-manufacturing is the interfacing of multiple components and featuresacross multiple length scales. In general, human beings typically interact withdevices with dimensions ranging from millimeter to meter ranges. Roboticsystems can be easily and reliably designed to interface features andcomponents down to micron levels. However, finer interfacing typically requiresmore costly and esoteric closed loop positioning systems such as mask alignersand scanning electron microscopes having vibration isolation mechanisms and insome cases complex laser interferometric position sensors. The bulk, cost, and time consuming operation ofthese instruments and processes often preclude their use in mass production andassembly techniques. Further, instruments that can manipulate objects at thesub-micron and nanometer scale are often not adapted to handle objects atlarger length scales. Therefore, there is an urgent need for designing novelmethods for performing for self-alignment and assembly of objects with micronand nanometer-level features.
