  • Patent number: 7665981
    Abstract: The present is directed towards an imprint lithography system including, inter alia, a docking plate; a motion stage having a range of motion associated therewith, the range of motion having a periphery spaced-apart from the docking plate a first distance; and a body, having first and second opposed sides spaced-apart a second distance, selectively coupled between the docking plate and the motion stage, the first distance being greater than the second distance to minimize a probability of a collision between the docking plate, the motion stage and the body while transferring the body between the docking plate and the motion stage.

  • Patent number: 7636999
    Abstract: A method of retaining a substrate to a wafer chuck. The method features accelerating a portion of the substrate toward the wafer chuck, generating a velocity of travel of the substrate toward the wafer chuck, and reducing the velocity before the substrate reaches the wafer chuck. In this manner, the force of impact of the portion with the wafer chuck is greatly reduced, which is believed to reduce the probability that the structural integrity of the substrate, and layers on the substrate and/or the wafer chuck, are damaged.

  • Patent number: 7635263
    Abstract: The present invention is directed towards a chucking system to hold a substrate, said system including, inter alia, a chuck body having first and second opposed sides, said first side including an array of fluid chambers arranged in rows and columns, said fluid chambers each comprising first and second spaced-apart recesses defining first and second spaced-apart support regions, with said first support region cincturing said second support region and said first and second recesses, and said second support region cincturing said second recess, with said substrate resting against said first and second support regions, with said first recess and a portion of said substrate in superimposition therewith defining a first chamber and said second recess and a portion of said substrate in superimposition therewith defining a second chamber, with each column of said first chambers and each row of said second chambers being in fluid communication with a differing source of fluid to control a flow of fluid in said array

  • Patent number: 7635445
    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.

  • Patent number: 7630067
    Abstract: The present invention features a method to determine relative spatial parameters between two coordinate systems, which may be a mold and a region of a substrate in which mold is employed to generate a pattern. The method includes sensing relative alignment between the two coordinate systems at multiple points and determines relative spatial parameters therebetween. The relative spatial parameters include a relative area and a relative shape.
