Patent ID: 8420499

Claim:
A method of forming a concave-convex pattern, comprising: forming a guide pattern on a base material, the guide pattern having a convex portion; forming a formative layer on the guide pattern, the formative layer including a plurality of sets of stacked structures, each of the stacked structures including a first layer and a second layer, the respective sets being configured so that a number of atomic layers in the first layers decreases as the guide pattern becomes further away, and a number of atomic layer in the second layers increases as the guide pattern becomes further away, the first layer including at least one element selected from a first metal element and a metalloid element, the second layer including a second metal element different from the first metal element; selectively leaving the formative layer only at side faces of the convex portions by performing etching on the formative layer; removing the guide pattern; and forming the concave-convex pattern in the base material by performing etching on the base material, with the remaining formative layer being used as a mask.
