Patent ID: 8252189

Claim:
A method for manufacturing a nano structure comprising: forming a stamp having a line pattern on a surface thereof, the line pattern including protrusions having a first width; pressing the protrusions of the stamp against a substrate to form a plurality of open channel pores between the stamp and the substrate; controlling a channel pore shape and/or size of the plurality of open channel pores by controlling an applied pressure on the stamp, wherein increasing the applied pressure results in the protrusions having a second width greater than the first width; forming at least one protruded portion in the substrate with an etchant that substantially fills the plurality of open channel pores, wherein the at least one protruded portion substantially corresponds to the line pattern of the stamp; forming a protective coating layer on at least a portion of the at least one protruded portion; and removing a portion of the substrate that is not covered with the protective coating layer by etching.
