摘要:
A lithographic apparatus includes at least one object support structure in a high vacuum chamber. The object support structure includes a carrier device in which a number of dividing walls are provided forming a number of compartments in the carrier device. At least one of the compartments is shielded from the high vacuum chamber and is provided with separate gas evacuating structures.
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:
A lithographic apparatus has an illumination system that conditions a radiation beam and a patterning device support that supports a patterning device. The patterning device patterns the radiation beam. The lithographic apparatus also has a substrate support that supports a substrate, a machine frame that supports the substrate support, a projection system that projects the patterned beam onto a target portion of the substrate, and a substrate support drive that moves the substrate support in at least one direction. The lithographic apparatus can have a reaction mass, a balance mass, a base frame, where the substrate support drive is configured to generate a force in the at least one direction between the substrate support and the reaction mass, the balance mass, or the support frame.

摘要:
A lithographic projection apparatus is presented herein that includes a collision protection system for protecting internal components against damage from a collision. The collision protection apparatus includes at least one damper for applying a braking force and/or for absorbing a collision force, reducing or eliminating any damage to delicate and costly parts. The collision protection apparatus can also monitor the position and velocity of a moving part to determine when a collision is likely to occur.

A portable device for attaching a connector to an optical fiber, the optical fiber having an end, the device comprising means for receiving the optical fiber at the end of the optical fiber; and a connector station for autonomously attaching the connector to the optical fiber.
摘要:
A substrate handler is provided. The substrate handler includes a support surface configured to carry a substrate and a pre-conditioning unit configured to pre-condition the substrate. The substrate handler is configured to move the substrate relative to a substrate table.
摘要:
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.
