Abstract:
1. A method of microminiaturizing a nano-structure, comprising the steps of: (a) providing a substrate and a layer including a nano cylindrical pore formed on said substrate; (b) depositing a deposit material on a top edge of said nano cylindrical pore to form a structure that extends radially inward from said top rim, placing said substrate on a movable platform at a non-zero tilt angle relative to an angle of incidence of said deposit material on said top rim, and rotating said movable platform at least once during deposition of said deposit material to deposit said deposit material around a circumference of said rim and thereby reduce a size of the top opening of the nano cylindrical pore; (c) passing a nano-structure-forming material through the reduced-size top opening to form a nano-structure on a surface of the substrate, said nano-structure having dimensions corresponding to dimensions of said reduced-size top opening; and (d) removing at least a portion of said layer, including said nano cylindrical pore.
