摘要:
The invention relates to an image sensor for detection of an aerial image formed by a beam of radiation in a lithographic projection apparatus for exposing a pattern onto a substrate held in a substrate plane by a substrate holder. The image sensor has an image detector and a lens. The lens is arranged to project at least part of the aerial image onto the image detector. The image sensor is positioned such within the substrate holder that the lens is positioned proximate the substrate plane.

The invention relates to an image for detection of an aerial pattern comprising spatial differences in radiation intensity in a cross section of a beam of radiation in a lithographic apparatus for exposing a substrate. The image sensor comprises a lens (5) arranged to form a detection image of the aerial pattern and an image detector (6) arranged to measure radiation intensities in a plurality, of positions in the detection image.

摘要:
An exposure apparatus including a movable table, a member, movably separate from the table and located on a top surface of the table, to provide a surface substantially co-planar with a top surface of an object in or on the table, a projection system configured to project a radiation beam onto a radiation-sensitive target portion of a substrate, and a liquid supply system configured to provide a liquid to a space between the projection system and the object.
摘要:
In a lithographic apparatus, a localized area of the substrate surface under a projection system is immersed in liquid. The height of a liquid supply system above the surface of the substrate can be varied using actuators. A control system uses feedforward or feedback control with input of the surface height of the substrate to maintain the liquid supply system at a predetermined height above the surface of the substrate.
摘要:
A lithographic projection apparatus is disclosed in which a space between the projection system and the substrate is filled with a liquid. An edge seal member at least partly surrounds the substrate or other object on a substrate table to prevent liquid loss when edge portions of the substrate or other object are, for example, imaged or illuminated.
