Chuck, in particular for use in a mask aligner
A chuck for aligning a first planar substrate in parallel to a second planar substrate includes a top plate having a top surface for arrangement of the first planar substrate. A bottom plate is at least one distance measuring sensor configured to measure a distance between the top surface of the top plate and a surface of the second planar substrate, and at least three linear actuators in contact with the top plate and the bottom plate. The method for setting a gap between the first and second planar substrate includes measuring the thickness of the first planar substrate and measuring between a surface of the second planar substrate and the top surface of the top plate. The tilt adjusts between a top surface of the first planar substrate or the chuck and the surface of the second planar substrate by using at least three linear actuators of the chuck.
ANTI-SLIPPERY STAMP LANDING RING
Apparatus and methods of performing nanoimprint lithography using an anti-slip landing ring are provided. In one embodiment, a process chamber for nanoimprint lithography is provided and includes a substrate support and a ring disposed on the substrate support. The ring has a top surface opposite the substrate support, and the top surface has a grid pattern. A bottom surface facing the substrate support has a different pattern compared to the grid pattern.
Imprint apparatus, imprint method, and article manufacturing method
An imprint apparatus comprises a mold holder configured to move while holding the mold, and a substrate holder including a plurality of suction regions for chucking the substrate and configured to move while holding the substrate. When performing the mold separation, among the plurality of suction regions, a suction force of a suction region at a position where the mold is to be separated from the imprint material is made weaker than a suction force of a suction region on a peripheral side of the substrate than the position where the mold is to be separated, and the mold holder is tilted after at least one of the mold holder and the substrate holder is moved by a predetermined amount so as to widen a gap between the mold and the substrate.

Method in which alignment control of a member and a substrate is effected with respect to an in-plane direction of the substrate and an uncured material in a state of bringing a member and the uncured material on a substrate into contact
A method in which alignment control of a member and a substrate is effected with respect to an in-plane direction of the substrate and an uncured material in a state of bringing a member and the uncured material on a substrate into contact with each other is cured. The method includes a step of bringing the member and the substrate near to each other while effecting the alignment control, based on a driving profile, after the alignment control is started, to bring the member and the uncured material into contact with each other, and then the uncured material is cured, and a step of increasing a gap between the member and the substrate, after the uncured material is cured, wherein the driving profile for the alignment control after the alignment control is started and at least one of before and after the member contacts the uncured material is changed.
LOW ENERGY E-BEAM CONTACT PRINTING LITHOGRAPHY
A method comprising contact-free positioning a template mask wafer having a template device pattern relative to a predetermined surface area section of a device pattern wafer. The template mask wafer includes a semitransparent layer. The method includes contact-free aligning one or more mask alignment marks of the template mask wafer with one or more alignment marks of the device pattern wafer and contacting the mask wafer on the device pattern wafer.
