NANOIMPRINTING MOLD, METHOD FOR PRODUCING THE NANOIMPRINTING MOLD, NANOIMPRINTING METHOD USING THE NANOIMPRINTING MOLD, AND METHOD FOR PRODUCING PATTERNED SUBSTRATES

摘要

A nanoimprinting mold includes: a mold main body having a fine pattern of protrusions and recesses on a surface thereof; and a mold release layer formed on the surface of the mold main body. The mold release layer is formed within a mold release layer forming region, which is a region of the mold main body that includes a patterned region where the fine pattern of protrusions and recesses is formed and has an outer edge positioned outside the outer edge of the patterned region. An outer peripheral mold release layer has a thickness distribution in which the thickness of the outer peripheral mold release layer is locally maximal at positions outside the outer edge of the patterned region, substantially continuously along the entire periphery. Thereby, it becomes possible to restrict the region in which resist flows during nanoimprinting, without employing a mesa type substrate.
