Patent number: 7090716Abstract: 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.Type: GrantFiled: October 2, 2003Date of Patent: August 15, 2006Assignees: Molecular Imprints, Inc., Board of Regents, The University of Texas SystemInventors: Ian M.
