摘要： A stamper of an embodiment includes: a base portion having a main surface; and a plurality of guides arranged on the main surface in mutually different first and second directions and serving as references of arrangement of a plurality of self-assembled dots. A distance between the guides in a third direction is within a range of an integer m1±0.05 times of a pitch of the plural self-assembled dots. The third direction corresponds to a third vector obtained by combining a first vector corresponding to the arrangement of the guides in the first direction and a second vector corresponding to the arrangement of the guides in the second direction. A distance between the plural guides in the first direction falls out of a range of an integer m2±0.15 times of the pitch of the plural self-assembled dots.

摘要： A patterning method includes steps of forming a first copolymer layer comprising a first diblock copolymer which has portions which are phase incompatible. The first copolymer layer is annealed to form a first phase pattern including a first phase dispersed in a second surrounding phase. The first copolymer is then etched forming a first topographic pattern that corresponds to the first phase pattern. A second copolymer layer of a second diblock copolymer is then formed over the first topographic pattern, and then annealed to generate a second phase pattern offset from the first topographic pattern. Etching is used to form a second topographic pattern corresponding to the second phase pattern. The first and second topographic patterns are then transferred to the substrate. The patterning method can be used, for example, to form patterned recording layers for magnetic storage devices.
