What is claimed is: 1. A method of separating a mold, included in a template, from a layer disposed on a substrate, said method comprising: applying a separation force to said template to separate said template from said layer; and facilitating localized deformation in said substrate, wherein facilitating further includes applying a positive pressure to first regions of said substrate and applying a vacuum to second regions of said substrate such that said vacuum constrains said substrate in second regions of said substrate as said positive pressure deforms first regions of said substrate in a first direction. 2. The method as recited in claim 1 wherein facilitating further includes facilitating localized deformation in response to said separation force. 3. The method as recited in claim 1 wherein facilitating further includes facilitating localized deformation of said substrate in a region in superimposition with said mold. 4. The method as recited in claim 1 wherein facilitating further includes said facilitating localized deformation of said substrate in a region in superimposition with said mold while avoiding deformation of areas of said substrate outside of said region. 5. The method as recited in claim 1 wherein said mold is adhered to said layer by an adhesion force with applying further including applying said separation force with a magnitude to overcome said adhesion force. 6. A method of separating a mold, included in a template, from a layer disposed on a substrate, said method comprising: applying a separation force to said template to separate said template from said layer; and facilitating localized deformation in said substrate, wherein facilitating further includes applying a vacuum to said substrate at a plurality of spaced-apart regions, a subset of which has a vacuum associated therewith that is less than the vacuum associated with the remaining regions of said plurality of spaced-apart regions. 7.
