  • Publication number: 20170282440
    Abstract: 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.

  • Publication number: 20170165898
    Abstract: In an embodiment, an imprint apparatus can include a substrate holder having a chucking region and a recessed support section; and a template holder, wherein the chucking region has more area as compared to a template region. In another embodiment, an imprint apparatus can include gas zones; and a gas controller that can be configured to adjust pressures within the gas zones to induce a convex curvature of a partial field of a workpiece used with the imprint apparatus. A method can include providing a workpiece within an imprint apparatus, wherein the workpiece includes a substrate and a formable material; and initially contacting a template with the formable material at a location spaced apart from the periphery of a partial field. In a particular embodiment, the method can further include modulating the substrate to form a convex shape contacting the template with the formable material.

  • Patent number: 9514950
    Abstract: Methods of increasing etch selectivity in imprint lithography are described which employ material deposition techniques that impart a unique morphology to the multi-layer material stacks, thereby enhancing etch process window and improving etch selectivity. For example, etch selectivity of 50:1 or more between patterned resist layer and deposited metals, metalloids, or non-organic oxides can be achieved, which greatly preserves the pattern feature height prior to the etch process that transfers the pattern into the substrate, allowing for sub-20 nm pattern transfer at high fidelity.

  • Publication number: 20150158240
    Abstract: 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.

  • Publication number: 20110165412
    Abstract: Forming an adhesive layer on a nanoimprint lithography template or a double-sided disk. Forming the adhesive layer on the double-sided disk includes immersing the double-sided disk in a liquid adhesive composition and removing the double-sided disk from the adhesive composition. The outer layer of the double-sided disk is a carbon overcoating or an intermediate layer. The adhesive composition is dried to form a first adhesion layer adhered directly to the carbon overcoating or intermediate layer on a first side of the disk and a second adhesion layer adhered directly to the carbon overcoating or intermediate layer on a second side of the disk. Forming the adhesive layer on the nanoimprint lithography template includes applying an adhesive material to the template, allowing the template to remain motionless, and rinsing a portion of the adhesive material from the template with a solvent, and drying the template.
