1. A lithographic apparatus, comprising:
- an illumination system that supplies a beam of radiation;
a patterning device that patterns the beam;
two or more movable chucks, each arranged to support a corresponding substrate;
a projection system that projects the patterned beam onto a target portion of one of the substrates;
a metrology system adjacent the projection system that aligns the substrate with the projection system as it enters the patterned beam; and
a loading device that places the substrates onto the chucks,wherein the chucks are independently movable so that one of the substrates is passed through the patterned beam, while another one of the substrates is moved between a loading system and projection system.

Abstract
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.

27. A carousel for use in a lithographic apparatus that comprises an illumination, patterning, and projection system that patterns a beam of radiation and projects the patterned beam onto a target portion of a substrate and a metrology system adjacent the projection system that ensures the substrate is aligned with the projection system, the carousel comprising:
-
two or more chucks, each arranged to support a corresponding one of the substrates; and a loading device that places the substrates onto the chucks; wherein the chucks are independently movable, so that one of the substrates is passed through the metrology system and the patterned beam, while another one of the substrates is moved between a loading system and the projection system.

28. A device manufacturing method, comprising:
-
patterning a beam of radiation provided by a illumination system using a patterning device; providing two or more movable chucks, each arranged to support a corresponding substrate; aligning a first one of the substrates with a projection system using a metrology system adjacent the projection system; projecting the patterned beam onto a target portion of a first one of the substrates with the projection system; placing the substrates onto the chucks using a loading device; and
independently moving a second one of the substrates between the loading device and the projection system, while the patterned beam is projected onto the first substrate. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)
