A motor includes a magnet assembly to generate a magnetic field. The field includes along the first direction parts which are alternately orientated in the first and the second direction. The parts extend in a third direction which is perpendicular to the first and the second direction. The motor further includes a first coil winding to carry a first current. The first coil winding to extend in the first direction between parts of the magnetic field orientated in the second direction, to generate the force in the first direction. The motor also includes a second coil winding to carry a second current. The second coil winding to extend in the first direction between parts of the magnetic field substantially orientated in the first direction, to generate the force in the second direction.

Methods and apparatus for maintaining the thermal equilibrium of a substrate and an immersion lithographic apparatus are disclosed using or having a timetable comprising information regarding the position, speed and/or acceleration of the substrate; and an evaporation controller and/or condensation controller acting to decrease localized evaporation and/or increase localized condensation in response to the information in the timetable. Evaporation of liquid from the surface of the substrate cools it down, while condensing liquid on its bottom surface heats the substrate locally.

The invention relates to a dual stage lithographic apparatus, wherein to substrate stages are constructed and arranged for mutual cooperation in order to perform a joint scan movement for bringing the lithographic apparatus from a first situation, wherein immersion liquid is confined between a first substrate held by the first stage of the said stages and a final element of a projection system of the apparatus, towards a second situation, wherein the said liquid is confined between a second substrate held by the second stage of the two stages and the final element, such that during the joint scan movement the liquid is essentially confined within said space with respect to the final element.
摘要:
An apparatus for changing an aggregate intensity of a light within an illumination field of a photolithography system having a blade structure and a first actuator. The blade structure is configured to be positioned along an optical path of the photolithography system between an illumination system and a reticle stage so that, when the illumination system provides the light having the illumination field, the blade structure is substantially at a center of the illumination field and a first portion of the light within the illumination field impinges upon the blade structure. The first actuator is coupled between a first portion of the blade structure and a frame of the photolithography system and is configured to move at least the first portion of the blade structure in a first direction so that a second portion of the light within the illumination field impinges upon the blade structure.

An imprinting method is disclosed that involves, in an embodiment, redistributing a volume of imprintable medium in a flowable state over a target portion of a surface of a substrate into regions of differing volume corresponding to regions of differing pattern density of an imprint pattern of a template, contacting the medium while in the flowable state with the template to form the imprint pattern in the medium, subjecting the medium to conditions to change the medium into a substantially non-flowable state, and separating the template from the medium while in the substantially non-flowable state.
摘要:
An imprinting method is disclosed, in which an embodiment involves subjecting an imprintable medium on a substrate to conditions such that the medium is at a first temperature so that it is in a flowable state, the imprintable medium comprising an imprint material selected from a group consisting of: a crystalline material and a polycrystalline material, pressing a template into the medium to form an imprint in the medium, cooling the medium to a second temperature such that the medium is in a substantially non-flowable state while the medium is contacted by the template, and separating the template from the medium while in the substantially non-flowable state.
摘要:
A uniformity correction module for improving the uniformity of a radiation distribution in a rectangular illumination slit having two longer sides and two shorter sides, including a plurality of movable blades arranged along each long side of the illumination slit and a chamber containing a fluid wherein said movable blades are at least partly immersed in said fluid, and wherein the difference between the refractive index of each blade and the refractive index of said fluid is sufficiently small to prevent significant reflection and refraction at the surface of each blade.
