Abstract:
1. A method for tiling patterned areas, the method comprising: a. depositing a predetermined thickness of a curable material on a substrate and exposing the curable material to an initial radiation treatment prior to contacting the curable material with a mold so as to form a cured base layer on the substrate having a thickness that is less than the predetermined thickness while leaving a remaining curable material over the base layer resulting from oxygen exposure during said initial treatment; b. contacting a first portion of the remaining curable material with a mold having a pattern; c. exposing the first portion of curable material contacted by the mold and a portion of the remaining curable material not contacted by the mold with a first treatment to cure the first portion of curable material contacted by the mold, wherein the portion of remaining curable material not contacted by the mold is exposed to oxygen and retains an uncured layer; d. removing the mold from the cured first portion of curable material to provide a patterned area in the cured first portion of curable material; e. contacting a second portion of the remaining curable material with the mold such that the mold overlaps a portion of the cured first portion of curable material and at least a portion of the uncured layer; f. exposing the second portion of curable material contacted by the mold and a portion of the remaining curable material not contacted by the mold with a second treatment which cures the second portion of curable material in contact with the mold; and g. removing the mold from the cured second portion of curable material to provide a patterned area in the cured second portion of curable material and to yield a seam between the patterned areas of the cured first portion of curable material and the cured second portion of curable material, wherein the seam has a dimension from about 50 nanometers to about 20 micrometers.
