  • Publication number: 20060032437
    Abstract: 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.

  • Publication number: 20050270312
    Abstract: The present invention is directed to a method for dispensing a total volume of liquid on a substrate, the method including, inter alia, disposing a plurality of spaced-apart droplets on a region of the substrate, each having an unit volume associated therewith, with an aggregate volume of the droplets in the region being a function of a volume of a pattern to be formed thereat.

  • Publication number: 20050072757
    Abstract: The present invention is directed toward a method of controlling a turbulent flow of a fluid between a substrate and a template, and more specifically, controlling a turbulent flow of a fluid between droplets disposed on a substrate and a template. To that end, the method further comprises the ingression and egression of the fluid through a first and second aperture, and in a further embodiment, a plurality of apertures, to create such a turbulent flow of the fluid.

  • Publication number: 20050074512
    Abstract: The present invention is directed toward a system for introducing a flow of a fluid between a mold, disposed on a template, and a substrate, the system including, a fluid supply system; and a chuck body having a baffle and first and second apertures, the first and second apertures disposed between the baffle and the template, with the first and second apertures in fluid communication with the fluid supply system to produce a turbulent flow of the fluid between the mold and said substrate.

  • Publication number: 20050072755
    Abstract: The present invention is directed toward a method for reducing pattern distortions in imprinting layers by reducing gas pockets present in a layer of viscous liquid deposited on a substrate. To that end, the method includes varying a transport of the gases disposed proximate to the viscous liquid. Specifically, the atmosphere proximate to the substrate wherein a pattern is to be recorded is saturated with gases that are either highly soluble, highly diffusive, or both with respect to the viscous liquid being deposited. Additionally, or in lieu of saturating the atmosphere, the pressure of the atmosphere may be reduced.
