    摘要: Described are methods for patterning a substrate by imprint lithography. Imprint lithography is a process in which a liquid is dispensed onto a substrate. A template is brought into contact with the liquid and the liquid is cured. The cured liquid includes an imprint of any patterns formed in the template. Alignment of the template with a previously formed layer on a substrate, in one embodiment, is accomplished by using scatterometry.

    摘要: The present invention is directed to a body having a first area and a second area separated by a recess. The recess is dimensioned to reduce, if not prevent, a liquid moving along a surface of the body from traveling between the first and second areas. One or more alignment marks may be positioned within one of the first and second areas. In this manner, the recess functions as a moat by reducing, if not preventing, a quantity of the liquid from being in superimposition with the alignment marks.

    摘要: 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.
