Abstract
A method of manufacturing an intermediate transfer surface includes depositing an array of etch stops on a conductive surface, etching the conductive surface to form mesas of the conductive surface separated by gaps, and coating the mesas with a dielectric coating. A method of performing microassembly includes forming an assembly of particles on an assembly plane, providing an intermediate transfer surface having an array of electrodes, applying a bias to the intermediate transfer surface to form an electrostatic field between the assembly plane and the intermediate transfer surface, and moving the intermediate transfer surface towards the assembly surface until the electrostatic field strength is strong enough to cause transfer of the assembly to the intermediate transfer surface.
