NANOSTRUCTURE ARRAY FABRICATION WITH A SIZE-CONTROLLABLE NATURAL LITHOGRAPHY

A simple technique for size-controllable nanostructure array formation has been developed, using self-assembled polystyrene beads whose diam eters can be arbitrarily reduced by reactive ion etching. We have prod uced a hole array of 83 and 157 nm diameter with 200 nm pitch on Si su bstrate, This technique can find potential applications in many areas of science and technology.
