  • Publication number: 20180117796
    Abstract: According to one embodiment, an imprint template manufacturing apparatus includes: a stage that support a template having a convex portion where a concavo-convex pattern is formed; a supply head that supplies a liquid-repellent material in liquid form to the template on the stage; a moving mechanism that moves the stage and the supply head relatively in a direction along the stage; and a controller that controls the supply head and the moving mechanism such that the supply head applies the liquid-repellent material to at least a side surface of the convex portion so as to avoid the concavo-convex pattern. The liquid-repellent material contains a liquid-repellent component and a non-liquid-repellent component that react with the surface of the template, a volatile solvent that dissolves the liquid-repellent component, and a fluorine-based volatile solvent that dissolves the non-liquid-repellent component.

  • Publication number: 20180022016
    Abstract: According to one embodiment, a template for imprint includes a base, a convex portion, and a liquid-repellent layer. The base has a main surface. The convex portion is provided on the main surface. The convex portion has an end surface on a side opposite to the main surface, and a concavo-convex pattern to be pressed against a liquid material to be transferred is formed on the end surface. The liquid-repellent layer is formed on at least the side surface of the convex portion so as to avoid the concavo-convex pattern. The liquid-repellent layer repels the liquid material to be transferred.

  • Publication number: 20180015497
    Abstract: According to one embodiment, an imprint template manufacturing apparatus includes a stage, a supply head, a moving mechanism, and a controller. The stage supports a template that includes a base having a main surface, and a convex portion provided on the main surface and having an end surface on a side opposite to the main surface. A concavo-convex pattern to be pressed against a liquid material to be transferred is formed on the end surface. The supply head supplies a liquid-repellent material in a liquid form to the template on the stage. The moving mechanism moves the stage and the supply head relative to each other in a direction along the stage. The controller controls the supply head and the moving mechanism such that the supply head applies the liquid-repellent material to at least the side surface of the convex portion so as to avoid the concavo-convex pattern.

  • Publication number: 20180016673
    Abstract: According to one embodiment, an imprint template manufacturing apparatus includes a support unit, a vaporization unit, and an adhesion preventing plate. The support unit supports a template that includes a base having a main surface, and a convex portion provided on the main surface and having an end surface. A concavo-convex pattern to be pressed against a liquid material to be transferred is formed on the end surface. The support unit supports the template with the convex portion facing downward. The vaporization unit is located below the template on the support unit and configured to vaporize a liquid-repellent material. The adhesion preventing plate is located below the template on the support unit and configured to allow the liquid-repellent material vaporized to adhere to the side surface of the convex portion of the template and to prevent it from adhering to the concavo-convex pattern.
