20100040718 | Template Having a Silicon Nitride, Silicon Carbide or Silicon Oxynitride Film - An imprint lithography template including, inter alia, a body having a first thickness associated therewith; a patterning layer, having a second thickness associated therewith, comprising a plurality of features, having a third thickness associated therewith. | 02-18-2010 |
20100201042 | Step and Repeat Imprint Lithography Processes - Methods of forming continuous layers on regions of a substrate are described. Generally, an imprint lithography template may contact liquid positioned on the substrate. The liquid may be cured forming a masking layer, and the imprint lithography template separated from the masking layer. Prior to separation, pressurized gas and/or vacuum may be applied between the template and the substrate. Additionally, during separation, pressurized gas and/or vacuum may be applied between the template and the substrate. | 08-12-2010 |
20100291257 | Template Having a Varying Thickness to Facilitate Expelling a Gas Positioned Between a Substrate and the Template - A nanoimprint lithography template including, inter alia, a body having first and second opposed sides with a first surface disposed on the first side, the second side having a recess disposed therein, the body having first and second regions with the second region surrounding the first region and the recess in superimposition with the first region, with a portion of the first surface in superimposition with the first region being spaced-apart from the second side a first distance and a portion of the first surface in superimposition with the second region being spaced-apart from the second side a second distance, with the second distance being greater than the first distance; and a mold disposed on the first side of the body in superimposition a portion of the first region. | 11-18-2010 |
20110171340 | Template Having a Varying Thickness to Facilitate Expelling a Gas Positioned Between a Substrate and the Template - A nanoimprint lithography template including, inter alia, a body having first and second opposed sides with a first surface disposed on the first side, the second side having a recess disposed therein, the body having first and second regions with the second region surrounding the first region and the recess in superimposition with the first region, with a portion of the first surface in superimposition with the first region being spaced-apart from the second side a first distance and a portion of the first surface in superimposition with the second region being spaced-apart from the second side a second distance, with the second distance being greater than the first distance; and a mold disposed on the first side of the body in superimposition a portion of the first region. | 07-14-2011 |
20110221095 | Step and Repeat Imprint Lithography Process - The present invention is directed to 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. In one embodiment, the imprint process is designed to imprint only a portion of the substrate. The remainder of the substrate is imprinted by moving the template to a different portion of the template and repeating the imprint lithography process. | 09-15-2011 |

20100072652 | IMPRINT LITHOGRAPHY SYSTEM AND METHOD - System, method and process for imprinting a substrate using controlled deformation of a substrate and/or a template. The substrate and/or template may be positioned in single wave formation or double wave formation during an imprint lithography process. | 03-25-2010 |
20100102469 | Strain and Kinetics Control During Separation Phase of Imprint Process - Systems and methods for improving robust layer separation during the separation process of an imprint lithography process are described. Included are methods of matching strains between a substrate to be imprinted and the template, varying or modifying the forces applied to the template and/or the substrate during separation, or varying or modifying the kinetics of the separation process. | 04-29-2010 |
20110001954 | CHUCKING SYSTEM WITH RECESSED SUPPORT FEATURE - In an imprint lithography system, a recessed support on a template chuck may alter a shape of a template positioned thereon providing minimization and/or elimination of premature downward deflection of outer edges of the template in a nano imprint lithography process. | 01-06-2011 |
