Abstract:
1. A method of fabricating an imprint mold for molding a structure, the method comprising: directing a first and a second flux for forming a first material and a second material, respectively, to a substrate to form a layered structure having alternating layers of the first and the second material; controlling a thickness of the first and the second layers by controlling the first and the second flux; cleaving the layered structure to form a cleavage face in which sections of the layers are exposed; and etching the exposed sections of the layers using an etch procedure that predominantly etches one of the first and the second materials to form the mold having an imprinting surface with at least one indentation for molding the structure; wherein a shutter is used to shutter a portion of at least one of the first and the second flux so that at least one of the layers has a thickness that varies along a portion of a length of the at least one layer.
