Conference paper


This paper proposes a novel process for micro-sphere assembly. Grooved substrate was prepared to give a controlled wettability of the surface and then it was drawn up from suspension in which φ 1μm-polystyrene spheres were dispersed. This process can produce position-controlled structure of micro-spheres because the suspension selectively spread in the groove due to the controlled wettability and constitute hexagonally-packed structure. Some factors that affect the coverage, such as groove depth and width, were examined by experiments and it was found that deeper grooves and slightly raised local humidity enhanced the selective spreading and thus the coverage.
