Abstract
A method and apparatus for assembling microstructures onto a substrate through fluid transport. The microstructures being shaped blocks self-align into recessed regions located on a substrate such that the microstructure becomes integral with the substrate. The improved method includes a step of transferring the shaped blocks into a fluid to create a slurry. Such slurry is then dispensed evenly or circulated over the top surface of a substrate having recessed regions thereon. The microstructure via the shape and fluid tumbles onto the surface of the substrate, self-aligns, and engages into a recessed region.
Claims8
A method of assembling a microstructure on a plastic substrate, the method comprising:
- providing a plastic substrate with at least one recessed region on a surface thereof;
- providing a plurality of functional blocks, each functional block having an integrated circuit device thereon, the plurality of functional blocks shaped to fit in the at least one recessed region at a selected orientation;
- and
- disposing at least one functional block among the plurality of functional blocks into the at least one recessed region by mechanical vibration.
