摘要:
An imprint apparatus molds an uncured resin on a substrate and cures the resin to form a pattern of the cured resin on the substrate. The apparatus includes a mold holding unit that holds the mold, a substrate holding unit that holds the substrate, a deforming unit that deforms the mold held by the mold holding unit into a convex shape toward the substrate, a driving unit that changes an attitude of the mold or the substrate during a releasing operation in which the mold deformed into the convex shape is released from the resin to thereby make the position of a contact region at which the mold is brought into contact with the resin movable, a measuring unit that acquires image information indicating a state of the contact region, and a control unit configured to control the operation of the driving unit based on the image information.

An imprint apparatus includes a deforming unit configured to deform the mold held by the mold holding unit into a convex shape toward the substrate; a driving unit configured to change an attitude of the mold or the substrate during a pressing in which the mold deformed is pressed against the uncured resin to thereby make a position of a contact region at which the mold is brought into contact with the uncured resin movable; a control unit configured to calculate a plane coordinates of a centroid of the contact region based on an image information of the contact region acquired by a measuring unit and to control an operation of the driving unit such that the plane coordinates position of the centroid is directed toward the plane coordinates position of the centroid of a pattern-forming region on the substrate, which has been calculated or has been acquired in advance.

An exposure apparatus, exposing a substrate via liquid, includes a projection optical system that projects a pattern of an original onto the substrate and a substrate stage that holds and moves the substrate. The substrate stage includes a chuck that holds the substrate, a top plate that surrounds the substrate held by the chuck, and a draining mechanism that drains liquid on the top plate. The top plate has a first area and a second area on the surface of the top plate. At least part of the first area is formed between the substrate held by the chuck and the second area. The contact angle of the first area with the liquid is smaller than the contact angle of the second area with the liquid. The draining mechanism drains liquid on the first area.

At least one exemplary embodiment is directed to an exposure apparatus for exposing a substrate. The exposure apparatus includes a movable substrate stage, a projection optical system configured to project light from an original and including a final optical element, and a nozzle member provided around the final optical element and including an opposing surface opposing the substrate. The substrate is exposed via liquid filled between a final surface of the projection optical system and the substrate, the projection optical system, and the original. The opposing surface includes a supply port, a first recovery port provided farther from an optical axis of the final optical element than the supply port, and a first portion and a second portion provided between the supply port and the first recovery port. The distance between the first portion and the substrate is longer than the distance between the supply port and the substrate.

At least one exemplary embodiment is directed to an exposure apparatus configured to expose a substrate through a liquid comprising a projection optical and a nozzle unit. The nozzle unit has a liquid recovery port recovering the liquid and a liquid supply port arranged between a final lens and the liquid recovery port and supplying the liquid. A static contact angle of an outer-side second portion of the nozzle unit surface than the liquid recovery port with respect to the liquid is larger than that of an inner-side first portion of the nozzle unit surface than the liquid recovery port by 20° or more. A sliding angle of the second portion with respect to the liquid is 20° or less.
