Patent ID: 7195732

Claim:
A method for fabricating an article from an object material including an object fine surface structure thereon having an object size, the method comprising: fabricating a first mold from a first material, said first mold including a fine surface structure corresponding to the object fine surface structure and having a first size less than the object size; fabricating a second mold by transferring the fine surface structure of the first mold to a second material so that the fine surface structure transferred to the second material has a second size greater than the first size and less than the object size; fabricating the article by transferring the fine surface structure of the second mold to the object material so that the fine surface structure transferred to the object material has the object size, wherein the fabricating of the second mold comprises: applying a first curable resin onto the first mold to cover the fine surface structure thereof, and pressing the second material against the first mold with the first curable resin in between to transfer the fine surface structure of the first mold to the first curable resin; curing at least a portion of the first curable resin; separating the first curable resin from the first mold with the first curable resin being bonded with the second material; and transferring the fine surface structure of the first curable resin to the second material by dry-etching to form the second mold; and the fabricating of the article comprises: applying a second curable resin onto the second mold to cover the fine surface structure thereof and pressing the object material against the second mold with the second curable resin in between to transfer the fine surface structure of the second mold to the second curable resin; curing at least a portion of the second curable resin; separating the second curable resin from the second mold with the second curable resin being bonded with the object material; and transferring the fine surface structure of the second curable resin to the object material by dry-etching to form the article.
