  • Patent number: 11415882
    Abstract: A template for imprint comprises a main body having a bottom surface, a middle surface on a portion protruding relative to the bottom surface, and a pattern surface on a portion protruding relative to the middle surface, the pattern surface having an uneven pattern, wherein an outer edge of the pattern surface has a jigsaw shape, wherein a light-shielding member having a light transmittance lower than a light transmittance of the main body is disposed on the middle surface to surround the outer edge of the pattern surface in a plan view as viewed from the pattern surface, and wherein an outer edge of light-shielding member defines four sides having a shape in which a center of each side bulges outward with respect to a rectangle surrounding the outer edge of the pattern surface in the plan view, and wherein the shape of each side bulges outwardly in a stepwise manner from the ends of each side to the center of each side.

  • Patent number: 6087048
    Abstract: Disclosed is a method of producing a block mask, which is employed in an electron-beam lithography apparatus, with high precision irrespective of the size of openings. The electron-beam lithography apparatus is of a type that produces a unit pattern at a time by transmitting an electron beam through openings selected from among a plurality of kinds of openings of a block mask, links the unit pattern with a previous one, and repeats this process to delineate a desired pattern. The method consists of four steps. At the first step, a resist is applied to the surface of a substrate of a block mask. At the next step, the resist is exposed to delineate patterns of a plurality of kinds of openings. At the next step, the exposed resist is developed. At the next step, the substrate of the block mask is etched.
