  • Patent number: 9360751
    Abstract: An imprinting stamp and a nano-imprinting method using the imprinting stamp are provided. The imprinting stamp includes a first substrate; one or more field regions on the first substrate, the first substrate including nano-patterns; and a first dummy pattern region on the first substrate and adjacent to the field region, the dummy pattern region including first dummy patterns having greater dimensions than that of the nano-patterns, the first dummy patterns being a plurality of polygons, each of the polygons having a vertex pointing in a first direction proceeding from the field region toward the first dummy pattern region.
