摘要:
A lithographic apparatus including a barrier system and a device manufacturing method using such a lithographic apparatus. The barrier system is used to maintain a protected volume of gas within a barrier. The protected volume may be maintained when different components of the lithographic apparatus move relative to each other. The barrier system may be used in different locations within the lithographic apparatus. The geometry of the barrier affects how efficiently the protected volume is maintained, especially at high speeds. The geometry reduces the amount of ambient gas entering the protected volume from outside the barrier.

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,

A substrate holder (100) for a lithographic apparatus has a planarization layer (108) provided on a surface thereof. The planarization layer provides a smooth surface for the formation of a thin film stack (200) forming an electronic component. The thin film stack comprises an (optional) isolation layer (201), a metal layer (202) forming an electrode, a sensor, a heater, a transistor or a logic device, and a top isolation layer (203).
摘要:
Substrate holder (100) for use in a lithographic apparatus, the substrate holder comprising a main body having a first surface and a second surface opposite the first surface. A plurality of first burls are provided on the first surface, the first burls having end surfaces to support a substrate. A plurality of second burls are provided on the second surface to support the substrate holder on a structure. The plurality of first burls each comprise a lower body portion protruding from the first surface and an upper body portion above the lower body portion, the lower body portions comprise a different material from the upper body portions, and the upper body portions comprise diamond-like carbon.
