ABSTRACT:
Abstract: A method of rapidly assembling many discrete microelectronic or micro-mechanical devices 56 (FIG. 2 ) in a precise configuration (FIG. 8f). The devices are placed randomly on a template (FIG. 3 ) consisting of a pair of oppositely charged planar electrodes. The upper electrode contains a multiplicity of apertures. The template is vibrated and the devices are attracted to the apertures and trapped thereat. The shape of a given aperture determines the number, orientation, and type of device that it traps. The process is completed by mechanically and electrically connecting the devices. The present method for serf-assembly allows many sub-millimeter sized electronic components or other particles to be rapidly assembled into a predetermined configuration. The method relies on vibration and weak electrical or magnetic forces.
