摘要:
Disclosed herein is an automatic fluid dispensing method and system for dispensing fluid on the surface of a plate-like material, or substrate, including a semiconductor wafer for imprint lithography processes. The dispensing method uses fluid dispenser and a substrate stage that may generate relative lateral motions between a fluid dispenser tip a substrate. Also described herein are methods and devices for creating a planar surface on a substrate using a substantially unpatterned planar template.

Edge field patterning of a substrate having full fields and partial fields may include patterning using a template having multiple mesas with each mesa corresponding to a field on the substrate. Polymerizable material may be deposited solely between the template and the full fields of the substrate. A non-reactive material may be deposited between the template and partial fields of the substrate.

The present invention is directed towards a choice of the shape of the patterned fields for Level 0 (patterned by imprint or photolithography or e-beam, etc.) and Level 1 (patterned by imprint) such that these shapes when tessellated together eliminate the open areas causes by the moats.
摘要:
Adaptive imprint planarization provides a surface having desired shape characteristics. Generally, topography of a first surface is mapped to provide a density map. The density map is evaluated to provide a drop pattern for dispensing polymerizable material on the first surface. The polymerizable material is solidified and etched to provide a second surface having the desired shape characteristics. Additionally, adaptive imprint planarization compensates for parasitic effects of the imprinting process.
摘要:
A method of patterning a substrate comprising a plurality of fields, including, inter alia, positioning a first volume of fluid on a first subset of the plurality of fields of the substrate, with the first volume of fluid being subjected to a first evaporation time; positioning a second volume of fluid on a second subset of the plurality of fields of the substrate, differing from the first subset, with the second volume of fluid being subjected to a second evaporation time, differing from the first evaporation time; and patterning the first and second subsets of the plurality of fields, with the first subset of the plurality of fields being patterned prior to the second subset of the plurality of fields being patterned, with a volume associated with the second subset of the plurality of fields being greater than a volume associated with the first subset of the plurality of fields to compensate for the second evaporation time being greater than the first evaporation time.

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.
摘要:
Systems to control movement of a template during an imprint lithography process are described. The systems include an orientation stage having an inner frame, and outer frame, and a plurality of actuators coupled between the inner frame and the outer frame to vary translational motion and impart angular motion about a plurality of axes.
摘要:
Imprint lithography templates for patterning substrates are described. The templates include a section having a mold a first pattern of alignment forming areas and template alignment marks. The additional sections are generally devoid of a mold. One or more of the additional section may include the first pattern of a second pattern of alignment forming areas and template alignment marks. The second pattern may correspond to the first pattern.

The present invention is directed towards a method for determining deformation parameters that a patterned device would undergo to minimize dimensional variations between a recorded pattern thereon and a reference pattern, the method including, inter alia, comparing spatial variation between features of the recorded pattern with respect to corresponding features of the reference pattern; and determining deformation forces to apply to the patterned device to attenuate the dimensional variations, with the forces having predetermined constraints, wherein a summation of a magnitude of the forces is substantially zero and a summation of moment of the forces is substantially zero.
