FINE CONCAVO-CONVEX STRUCTURE PRODUCT, HEAT-REACTIVE RESIST MATERIAL FOR DRY ETCHING, MOLD MANUFACTURING METHOD AND MOLD

摘要

A fine concavo-convex structure product (10) is provided with an etching layer (11), and a resist layer (12) comprised of a heat-reactive resist material for dry etching provided on the etching layer (11), a concavo-convex structure associated with opening portions (12a) formed in the resist layer (12) is formed in the etching layer (11), a pattern pitch P of a fine pattern of the concavo-convex structure ranges from 1 nm to 10 μm, a pattern depth H of the fine pattern ranges from 1 nm to 10 μm, and a pattern cross-sectional shape of the fine pattern is a trapezoid, a triangle or a mixed shape thereof. The heat-reactive resist material for dry etching has, as a principal constituent element, at least one species selected from the group consisting of Cu, Nb, Sn, Mn, oxides thereof, nitrides thereof and NiBi.
