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...http://www.google.de/patents/US6864570?utm_source=gb-gplus-sharePatent US6864570 - Method and apparatus for fabricating self-assembling microstructures
