Patent number: 10663869Abstract: An imprinting system and method. An illumination system for imprinting, during a first period of time, that illuminates a first portion of boundary region that surrounds a pattern region with a thickening dosage of light that is within a first dose range, such that the fluid in the first portion of the boundary region does not solidify but does increase a viscosity of the fluid.

Patent number: 10124529Abstract: Imprint lithography templates having leading and trailing edge borders are provided that achieve zero-gap imprinting between adjacent fields with full-feature height features provided in the pattern exclusion zones (PEZ) located between such fields. The leading edge borders include dummy features, e.g., elongated features directionally oriented parallel to the mesa edge, while the trailing edge border includes a recess extending to the mesa edges. When used in a step-and-repeat process, the trailing edge border overlaps edge portions of an adjacent imprinted field that were previously patterned by the leading edge border of the template, producing full-feature height features in the pattern exclusion zones between such fields, and avoiding gaps or open areas between such fields that otherwise lead to non-uniformity of downstream processes such as etch processes and CMP.Type: GrantFiled: December 10, 2014Date of Patent: November 13, 2018Assignee: Canon Nanotechnologies, Inc.Inventors: Gaddi S. Haase, Kosta S. Selinidis, Zhengmao Ye

Patent number: 10095106Abstract: A nanoimprint lithography method to remove uncured pretreatment composition from an imprinted nanoimprint lithography substrate. The method includes disposing a pretreatment composition on a nanoimprint lithography substrate to form a pretreatment coating and disposing discrete portions of imprint resist on the pretreatment coating, each discrete portion of the imprint resist covering a target area of the nanoimprint lithography substrate. A composite polymerizable coating is formed on the nanoimprint lithography substrate as each discrete portion of the imprint resist spreads beyond its target area, and the composite polymerizable coating is contacted with a nanoimprint lithography template. The composite polymerizable coating is polymerized to yield a composite polymeric layer and an uncured portion of the pretreatment coating on the nanoimprint lithography substrate, and the uncured portion of the pretreatment coating is removed from the nanoimprint lithography substrate.Type: GrantFiled: January 30, 2017Date of Patent: October 9, 2018Assignee: Canon Kabushiki KaishaInventors: Timothy Brian Stachowiak, Weijun Liu, Niyaz Khusnatdinov, Zhengmao Ye, Toshiki Ito
