摘要:
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,
摘要:
An apparatus for improving vibration isolation for a vibration sensitive device, such as metrology device or lithographic apparatus is disclosed. The apparatus comprises a module frame for supporting a projection module of the vibration sensitive device; and an intermediate frame for supporting an object support system of the vibration sensitive device, said object support system being configured for supporting an object. The intermediate frame is suspended from the module frame with a connection between the module frame and the intermediate frame being stiff in at least a first direction, the first direction being perpendicular to a main surface plane of said object.
