Abstract:
PURPOSE: A lithographic apparatus having parts with a coated film adhered thereto is provided top protect a negative effect from an UV radiation and an immersion fluid by supporting the coating on at least part of lithography apparatus. CONSTITUTION: A lighting system(IL) conditions radiation beam. A patterning device supporter(MT) supports a patterning device(MA). A substrate supporter supports the substrate. A projection system(PS) projects the patterned radiation beam on the target on the substrate. The adhesive film supports the coating on at least part of a lithography apparatus.
Abstract:
PROBLEM TO BE SOLVED: To provide a support in which measures are taken to reduce bending of a substrate during loading.SOLUTION: A support for an object has a support surface configured to support the object. The support surface includes a main part and a moveable part. The moveable part of the support surface is moveable between a retracted position and an extended position. In the retracted position, the moveable part of the support surface is substantially in the same plane as the main part of the support surface. In the extended position, the moveable part of the support surface protrudes from the plane of the main part of the support surface.
Abstract:
PROBLEM TO BE SOLVED: To provide a lithography projection apparatus having an exposure device and a measurement device the accuracy and the device manufacturing method of which have been improved. SOLUTION: The exposure device projects patterned beams to the target part of a first substrate and on the other hand, the measurement device projects measurement beams to the target part of a second substrate. When a movable part of the device moves, due to the displacement of air, for example, a disturbance is caused to occur at the other movable part of the device. This error can be corrected by calculating a correction signal that is a function of a state of either or both of the movable parts. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract:
A support for an object having a support surface configured to support the object; wherein the support surface includes a main part and a moveable part, the moveable part of the support surface being moveable between a retracted position in which the moveable part of the support surface is adapted to be substantially in the same plane as the main part of the support surface and an extended position in which the moveable part of the support surface protrudes from the plane of the main part of the support surface.
Abstract:
On-the-Fly leveling in a lithographic apparatus is conducted using a setpoint derived by filtering the output of the combination of the output of a level sensor and another position sensor (LVDT or IFM). The level sensor may include look-ahead. The filter may be a low pass filter to cut-off level variations of wavelength shorter than the width of the slit during a scanning exposure. The filter may also be selected to reduce cross-talk between tilt movements and horizontal displacements.
Abstract:
A support apparatus for a lithographic apparatus has an object holder and an extraction body radially outward of the object holder. The object holder is configured to support an object. The extraction body includes an extraction opening configured to extract fluid from a top surface of the support apparatus. The extraction body is spaced from the object holder such that the extraction body is substantially decoupled from the object holder. The extraction body comprises a projection configured such that it surrounds the object holder and such that, in use, a layer of liquid is retained on the projection and in contact with an object supported on the object holder.
Abstract:
A lithographic projection apparatus comprises an exposure system and a measurement system. The exposure system projects a patterned beam onto a target portion of a first substrate, while the measurement system projects a measurement beam on a target portion of a second substrate. Movement of a movable part of the apparatus generates a disturbance in a position of another movable part of the apparatus, e.g. due to displacement of air. This error can be compensated by calculating a compensation signal which is a function of states of one or both of the movable parts.
