Abstract

A system for controlling a volume of liquid on a mold that features a body defining a volume with an aperture formed into the body and positioned proximate to the mold. A pump system is in fluid communication with the body, and the aperture and the pump system are established to create a stream of fluid moving between the mold and the volume. In this manner a quantity of fluid is removed while retained upon the mold is a desired portion of the fluid to undertake imprint lithographic processes.
