  • System to control an atmosphere between a body and a substrate
    Patent number: 7316554
    Abstract: The present invention is directed towards a system to control an atmosphere about a substrate, the system including, inter alia, a body spaced-apart from a surface of the substrate a distance; a supply of fluid coupled to introduce a flow between the body and the substrate; and a wall coupled to the body to create a resistance of the flow between first and second regions of the substrate, with a position of the wall being varied in response to a decrease in a magnitude of the distance.
    Type: Grant
    Filed: September 21, 2005
    Date of Patent: January 8, 2008
    Assignee: Molecular Imprints, Inc.
    Inventors: Yeong-Jun Choi, Byung-Jin Choi
  • METHOD FOR EXPELLING GAS POSITIONED BETWEEN A SUBSTRATE AND A MOLD
    Publication number: 20070228589
    Abstract: The present invention is directed towards a method of expelling a gas positioned between a substrate and a mold, the substrate and the mold further having a liquid positioned therebetween.

  • Method to control an atmostphere between a body and a substrate
    Publication number: 20070063384
    Abstract: The present invention is directed towards a method of controlling an atmosphere about a substrate, the method including, inter alia, positioning a body a distance from a surface of the substrate, the body having a wall coupled thereto placed in a position to create a flow resistance of a fluid between first and second regions of the substrate; and altering the position of the wall such that when a magnitude of the distance between the body and the surface of the substrate is decreased, a probability of the wall contacting the substrate is minimized.

  • Method of separating a mold from a solidified layer disposed on a substrate
    Publication number: 20060172549
    Abstract: The present invention is directed towards a method of separating a mold, included in a template, from a layer disposed on a substrate, the method including, inter alia, applying a separation force to the template to separate the template from the layer; and facilitating localized deformation in the substrate to reduce the separation force required to achieve separation.
