Abstract:
1. A micropattern forming method for continuously forming micropatterns on a substrate, the micropatterns each corresponding to a transfer micropattern formed on a mold, the micropattern forming method comprising: a first covering step of covering a surface of the substrate with a film of a transfer material; a first transfer step of transferring the transfer micropattern onto the transfer material formed in the first covering step by pressing the mold against the substrate having the film of the transfer material provided on its surface by the first covering step; a first micropattern forming step of forming a micropattern on the substrate by etching after the transfer of the micropattern by the first transfer step, the micropattern corresponding to the transfer micropattern on the mold; a first removal step of removing the transfer material provided in the first covering step after the formation of the micropattern by the first micropattern forming step; a second covering step of covering surface portions of the substrate with a film of the transfer material, after the removal of the transfer material in the first removal step; a second transfer step of transferring the transfer micropattern onto the transfer material formed in the second covering step by pressing a mold against the substrate having the film of the transfer material provided on its surface by the second covering step; a second micropattern forming step of forming a micropattern on the substrate by etching after the transfer of the micropattern by the second transfer step, the micropattern corresponding to the transfer micropattern on the mold; and a second removal step of removing the transfer material provided in the second covering step after the formation of the micropattern by the second micropattern forming step; wherein the micropattern formed by the first micropattern forming step and the micropattern formed by the second micropattern forming step comprise a continuous micropattern.
