Abstract:
1. A method of forming a layer on a substrate, said method comprising: disposing a curable liquid solely on said substrate as a predetermined pattern of a plurality of spaced-apart droplets, said curable liquid provided with a viscosity of less than about 20 centipoises, measured at 25° C., and a surface area less than the surface area of an imprint lithography template; contacting said curable liquid with a patterning area of said imprint lithography template to spread said curable liquid in said plurality of spaced-apart droplets such that adjacent droplets of said plurality of spaced-apart droplets merge together to form a contiguous layer of said curable liquid over a region of said substrate in superimposition with said patterning area and substantially fill a contiguous gap defined between said template and said substrate with said curable liquid, with said plurality of spaced-apart droplets being arranged in said predetermined pattern to minimize trapping of a gas in said contiguous layer as said droplets merge to form said contiguous layer; and solidifying said curable liquid in said contiguous layer to form a solidified layer by curing said curable liquid with light passing through said imprint lithography template.
