摘要:
A substrate handler for moving a substrate relative to a substrate table of a lithographic apparatus. The substrate handler comprises at least one support surface or platform adapted to carry a plurality of independent substrates simultaneously. The substrate handler adapted to load substrates onto and unload substrates from the substrate table before and after exposure.

Embodiments of the invention relates to a substrate handler for handling a substrate, including a conditioning device for conditioning the substrate. In an embodiment, the substrate handler includes a displacing device configured to displace the substrate in a direction substantially parallel to the support surface, wherein the displacing device is configured to displace the substrate during the conditioning process from one conditioning position to one or more other conditioning positions. According to another embodiment of the invention, the substrate handler includes a float device for providing an air bed above a support surface of the substrate handler, the substrate handler being configured to support the substrate on an air bed during conditioning of the substrate.
摘要:
Substrate processing apparatus includes a lithographic apparatus which comprises an illumination system for supplying a projection beam of radiation, an array of individually controllable elements serving to impart the projection beam with a pattern in its cross-section, and a projection system for projecting the patterned beam onto a target portion of a substrate. The processing apparatus also includes a substrate supply arranged to output at least one unbroken length of substrate, and a substrate conveying system arranged to convey each outputted unbroken length of substrate from the substrate supply and past the projection system such that the projection system is able to project the patterned beam onto a series of target portions along each unbroken length of substrate. In certain embodiments, long lengths of substrate are supplied from a roll, but alternatively a series of separate sheets can be supplied.
摘要:
A lithographic method and apparatus comprises an illumination system that supplies a beam of radiation, a patterning device that patterns the beam, and a projection system that projects the patterned beam onto a target portion of a substrate. A metrology system is provided adjacent the projection system for aligning the substrate with the projection system. Two or more movable chucks are each arranged to support a substrate and move between a loading device and the projection system. The chucks are independently movable so that one substrate can be passed through the metrology system and patterned beam while the other substrates are moved between the loading system and projection system.

An apparatus, method, and system is provided to condition a substrate. The apparatus can include a substrate handler, an array of diodes, and a projection system. The substrate handler can include a conditioning device, a float device, and a displacing device. The array of diodes can be configured to provide a patterned radiation beam, where the projection system projects the patterned radiation beam onto a target portion of a conditioned substrate.
摘要:
The mask in a lithographic apparatus is clamped on a first side using a first clamping device and on a second side, different from the first side, using a second clamping device. The clamping forces are preferably applied using thin membranes. The first clamp clamps the substrate in directions parallel to the plane of the patterning device, perpendicular to the plane of the patterning device and rotationally. The second clamping device clamps the patterning device only in directions parallel to the plane of the substrate.
