Abstract: 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.

Abstract: A support table, a method of loading a substrate, a lithographic apparatus and a method of manufacturing a device using a lithographic apparatus are disclosed. In one arrangement, a support table is configured to support a substrate. The support table has a base surface. The base surface faces a bottom surface of the substrate when the substrate is supported by the support table. One or more gas cushion members are provided above the base surface. Each of the gas cushion members includes a recess. The recess is shaped and configured such that a lowering of the substrate into a position on the support table at which the substrate is supported by the support table causes a localized build-up of pressure within the recess. The localized build-up of pressure provides a localized gas cushioning effect during the lowering of the substrate,

Abstract: The present invention provides a tubular linear actuator, comprising: a tubular coil assembly comprising multiple tubular coils arranged next to each other in longitudinal direction of the tubular linear actuator and concentric with respect to a longitudinal axis of the tubular linear actuator, and a magnet assembly comprising a series of permanent magnets with alternating polarization direction extending in the longitudinal direction, wherein the magnet assembly is at least partially arranged in the coil assembly and movably with respect to the coil assembly, wherein the tubular coils comprise edge windings.
