摘要： A lithographic apparatus that includes an illumination system that conditions a radiation beam, a first stationary plate having a first surface, and a reticle stage defining, along with the first stationary plate, a first chamber. The reticle stage supports a reticle in the first chamber, and the reticle stage includes a first surface spaced apart from a second surface of the first stationary plate, thereby defining a first gap configured to suppress an amount of contamination passing from a second chamber to the first chamber. The first stationary plate is between the reticle stage and both the illumination system and a projection system configured to project a pattern imparted to the radiation beam by the patterning device onto a substrate.

摘要： An object stage that includes a first structure and a second structure movable relative to the first structure. The second structure is configured to support an object. The object stage also includes a seal plate movably coupled to the first structure or the second structure, but not both. Further, the object stage includes an actuator configured to move the seal plate such that a substantially constant gap is defined between the seal plate and the first structure or second structure that is not coupled to the seal plate.

摘要： Designs are provided to reduce the possibility of contaminant particles with a large range of sizes, materials, travel speeds and angles of incidence reaching a particle-sensitive environment. According to an aspect of the disclosure, there is provided an object stage comprising first and second chambers, a first structure having a first surface, and a second structure. The second structure is configured to support an object in the second chamber, movable relative to the first structure. The second structure comprises a second surface opposing the first surface of the first structure thereby defining a gap between the first structure and the second structure that extends between the first chamber and the second chamber. The second structure further comprises a third surface within the first chamber. The object stage further comprises a trap disposed on at least a portion of the third surface, the trap comprising a plurality of baffles.

摘要： A positioning system for positioning an object. The positioning system includes a stage, a balance mass and an actuator system. The stage is for holding the object. The actuator system is arranged to drive the stage in a first direction while driving the balance mass in a second direction opposite to the first direction. The stage is moveable in the first direction in a movement range. When the stage is moving in the first direction and is at an end of the movement range, the positioning system is arranged to collide the stage frontally into the balance mass.

摘要： A method for positioning a substage (9), supported by a main stage (5), relative to a reference object, the substage moveable in a direction (7) between a first and second position relative to the main stage. The method includes positioning the first stage using a passive force system that is activated by positioning the main stage. The passive force system includes two magnet systems (119, 121), each magnet system being configured to apply a force in the direction to the first stage with respect to the second stage in a non-contact manner, the forces resulting in a resultant force applied to the first stage in the direction by the passive force system. A magnitude and/or a direction of the resultant force depends on the position of the first stage relative to the second stage, and the first stage has a zero-force position between the first and second position in which the resultant force is zero.

摘要： A lithographic apparatus comprises a system. The system comprises a first part, a second part and an energy absorbing element. The second part is configured to move relatively to the first part. The system has a gap located between the first part and the second part during an operation mode of the system. The energy absorbing element is for absorbing energy between the first part and the second part when the first part and the second part crash onto each other in a failure mode of the system. The energy absorbing element is outside the gap.

摘要： A substrate stage is used in a lithographic apparatus. The substrate stage includes a substrate table constructed to hold a substrate and a positioning device for in use positioning the substrate table relative to a projection system of the lithographic apparatus. The positioning device includes a first positioning member mounted to the substrate table and a second positioning member co-operating with the first positioning member to position the substrate table. The second positioning member is mounted to a support structure. The substrate stage further comprises an actuator that is arranged to exert a vertical force on a bottom surface of the substrate table at a substantially fixed horizontal position relative to the support structure.

摘要： An object stage bearing system can include an object stage, a hollow shaft coupled to the object stage, and an in-vacuum gas bearing assembly coupled to the hollow shaft and the object stage. The in-vacuum gas bearing assembly can include a gas bearing, a scavenging groove, and a vacuum groove. The gas bearing is disposed along an inner wall of the in-vacuum gas bearing assembly and along an external wall of the hollow shaft. The scavenging groove is disposed along the inner wall such that the scavenging groove is isolated from the gas bearing. The vacuum groove is disposed along the inner wall such that the vacuum groove is isolated from the scavenging groove and the gas bearing.
