Method for reducing adhesion forces between an imprinting material and a mold, and use of an imprinting composition

摘要

A method and composition features improved wetting characteristics while allowing preferential adhesion and release characteristics with respect to a substrate and a mold having imprinting material disposed therebetween. The method includes coating a surface of the mold with a volume of surfactant containing solution. The surfactant in the solution includes a hydrophobic component consisting essentially of a plurality of fluorine-containing molecules. The compositions feature improved preferential adhesion and release characteristics with respect to a substrate and a mold having imprinting material disposed therebetween. The compositions facilitate bifurcation of the imprinting material into a surfactant-component-rich sub-portion and a surfactant-component-depleted sub-portion located between said surfactant-component-rich sub-portion and said substrate. A method is also disclosed that takes advantage of the characteristics of the composition.
