Abstract:
1. A method of forming a structure using a pattern transferred by a stamper, comprising: the step of forming a resist pattern having n physical steps (n: an integer greater than one) on the surface of an object substrate by a stamper having a plurality of physical steps; and selected one of the step of etching the surface of at least a recessed area of said resist pattern where said object substrate is exposed, and the step of forming a first structural material on the surface of said recessed area of said resist pattern where said object substrate is exposed; the step of forming at least a new area of said resist pattern where said object substrate is exposed, by removing the resist of said resist pattern to the height of the first physical step from the surface of said object substrate; selected one of the step of etching the surface of at least a recessed area of said resist pattern where said object substrate is exposed, and the step of forming at least a new structural material on the surface of the recessed area of said resist pattern including the surface of the structural material formed the immediately preceding time; and forming at least a new area where the object substrate is exposed, by removing the resist to the height of the second physical step from the surface of said object substrate of said resist pattern; said step of forming at least a new area being repeated up to n times.
