The imprint method includes changing the position of a detector that detects an alignment mark formed on a shot on a substrate; bringing a pattern formed on a mold into contact with an imprint material supplied on the shot on the substrate; and detecting the alignment mark using the detector after completion of the change in the position of the detector. Here, the contacting is started prior to completion of the change in the position of the detector.

The present invention provides an imprint apparatus which forms a pattern on an imprint material on a substrate by using a mold, including a first optical member interposed between an illumination optical system and a detection optical system, and a mold, and configured to guide a first light from the illumination optical system and a second light from the detection optical system to the mold, and a second optical member interposed between the first optical member and the detection optical system, and configured to transmit the second light which is reflected by a mark formed on the mold or a mark formed on the substrate and travels toward the detection optical system through the first optical member, and block the first light which travels toward the detection optical system through the first optical member.

Imprint apparatus including alignment and overlay measurement

An imprint apparatus cures an imprint material, while a pattern formed on a mold is kept in contact with the imprint material, thereby transferring the pattern onto the imprint material. The apparatus includes a measurement unit which performs, in parallel, alignment measurement in which a relative position between the mold and a shot region on the substrate, to which the pattern is to be transferred, is measured so as to align the mold and the shot region, and overlay measurement in which a relative position between a first pattern already formed in another shot region on the substrate using the mold, and a second pattern underlying the first patter is measured.

According to the embodiments, a template in which a main pattern is placed on a pattern-formed surface of a template substrate, the main pattern being formed by a concave and convex pattern, the template substrate being transparent to an electromagnetic wave with a predetermined wavelength is provided. The template includes a first mark in which line-shaped first concave patterns and first convex patterns are alternately placed in a width direction on the pattern-formed surface. The first convex pattern includes a first light-blocking portion and a first translucent portion. The first light-blocking portion is a region including a first side surface in the width direction and being covered with a metal film. The first translucent portion is a region including a second side surface in the width direction and being not covered with the metal film.

METHOD AND APPARATUS FOR EXPOSURE PATTERN CORRECTION AND EXPOSURE SYSTEM
20170023864 · 2017-01-26 ·

A method for correcting an exposure pattern on a substrate includes obtaining, based on the exposure pattern, displacement adjustment parameters for adjusting displacements of a worktable supporting the substrate in each of a first direction and a second direction, a rotation angle adjustment parameter for adjusting a rotation angle of the worktable in a rotation direction, and a gap adjustment parameter for adjusting a gap between the worktable and a mask plate. The first direction and the second direction are perpendicular to each other in a horizontal plane. The rotation direction is a direction in which the worktable rotates around a central axis of a base table supporting the mask plate. The method further includes moving the worktable based on the displacement adjustment parameters, the rotation angle adjustment parameter and the gap adjustment parameter.
