Electrostatic nanolithography probe actuation device and method

Abstract

Method and apparatus for selectively actuating a cantilevered probe for applying a compound to a substrate in nanolithography. A probe having a probe electrode and a substrate having a counter electrode are provided. Voltage applied to the probe electrode and/or counter electrode provides electrostatic attraction between them, moving a probe tip into sufficient proximity to the substrate to apply the patterning compound. Alternatively, a flexible cantilevered probe anchored to a holder includes a layer of conductive material forming a probe electrode. A counter electrode on the holder faces the probe electrode. The holder and probe are positioned so that a probe tip applies the compound to the substrate. The probe is disposed between the substrate and the counter electrode. An electrostatic attractive force generated between the probe electrode and the counter electrode flexes the probe and lifts the tip away from the substrate to suspend writing.
