Abstract:
1. A template for use in imprint lithography, comprising: a first ultraviolet wavelength radiation transparent material having a planar surface opposing a patterned surface comprising a plurality of recesses and a plurality of protrusions; a second ultraviolet wavelength radiation transparent material in contact with the planar surface of the first ultraviolet radiation transparent material; an adhesive composition bonding the first ultraviolet wavelength radiation transparent material to the second ultraviolet wavelength radiation transparent material, the adhesive composition having an index of refraction substantially similar to that of each of the first ultraviolet wavelength radiation transparent material and the second ultraviolet wavelength radiation transparent material; and an optically opaque material in contact with one of a periphery of the first ultraviolet wavelength radiation transparent material and scribe areas of the first ultraviolet wavelength radiation transparent material.
