Abstract
The present invention is directed to a template having a body including a surface with first and second regions. The first region has first wetting characteristics for a given material and the second region has second wetting characteristics for the given material. The first wetting characteristics differ from the second wetting characteristics. Specifically, the first region is formed from a surface treatment layer with a first surface energy to provide the first wetting characteristics. The second region is exposed portions of the body, typically quartz of fused silica, having a second surface energy associated therewith. The second surface energy is greater than the first surface energy to provide the second region with the second wetting characteristics.
