  • Publication number: 20180170089
    Abstract: A template for imprint lithography can include a body. The body can include a base surface and a recession extending from the base surface. The recession can have steps and a feature. The steps can include a distal step that is farther from the base surface as compared to any other step, each step having a corresponding height. The feature can include the distal step includes a rounded or tapered sidewall; a surface along a deepest part of the recession is non-planar; or the height corresponding to the distal step is different from an average height corresponding to remaining steps. The template can be used in an imprint lithography apparatus. The template can be used in manufacturing articles when patterning different layers at the same time. The template is well suited for forming 3D memory arrays.

  • Publication number: 20180169910
    Abstract: A method that can be used in the formation of replica imprint templates. The method can include providing a substrate with a substrate mesa defining an active region having a first area and a template with a template mesa defining a patterning region having a second area, where first area is larger than the second area. The template can then be positioned relative to the substrate such that patterning region of the template mesa overlaps the active region of the substrate mesa. The method can be used in forming a replica template. The formed replica template can be used to form a patterned layer on e.g. a semiconductor wafer in fabricating an electronic device. A system can be configured to carry out the methods.
