摘要
A method for fabricating sharp asperities. A substrate is provided which has a mask layer disposed thereon, and a layer of micro-spheres is disposed superjacent the mask layer. The micro-spheres are for patterning the mask layer. Portions of the mask layer are selectively removed, thereby forming circular masks. The substrate is isotropically etched, thereby creating sharp asperities.
