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 provision step of providing a covering member in a portion where the substrate is exposed by the transfer of the transfer micropattern in the first transfer step; a first removal step of removing the transfer material provided in the first covering step after covering the portion where the substrate is exposed with the covering member in the first provision 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 provision step of covering a portion were the substrate is exposed by the transfer of the transfer micropattern in the second transfer step with a covering member; a second removal step of removing the transfer material provided in the second covering step after covering the portion where the substrate is exposed with the covering member in the second provision step; a micropattern forming step of forming a micropattern on the substrate by etching after the removal of the transfer material by the second removal step, the micropattern corresponding to the transfer micropattern on the mold; and a third removal step of removing the covering members provided in the first and second provision steps after the formation of the micropattern by the micropattern forming step.
