Abstract
A number of distance control methods have been developed which allow the direct ablation capabilities of the ArF excimer laser to be applied to near-field optical methods of nanopatterning. Feedback systems based on evanescent field detection, capacitance and lateral atomic force sensing have been incorporated into our near-field optical nanofabrication system. Using these control techniques, structures were directly patterned on a variety of substrates with dimension on the order of 1 00 nm. These feedback technique are versatile enough to allow accurate distance control despite severe disturbances to the system caused by high energy excimer laser pulses.
