Abstract:
An extraction body (67) is for a support apparatus (WT) of a lithographic apparatus. The support apparatus is configured to support an object (W). The extraction body is formed with an opening (91) at a surface (69) thereof. The opening extends within the extraction body forming a first passageway (90). The first passageway is configured to fluidly communicate an extraction channel (92) in the extraction body to liquid between the surface and the object. A first pressure in the extraction channel is less than ambient pressure. At least a part of the first passageway is sized and dimensioned such that when the liquid enters the first passageway via the opening, a second pressure in the first passageway associated with surface tension of the liquid is lower than the first pressure such that at least a portion of the liquid is retained in the first passageway.
Abstract:
A lithographic apparatus is described, the apparatus comprising: n illumination system configured to condition a radiation beam; otary drive adapted to move a flexible patterning device along a closed loop trajectory, the closed loop trajectory having a straight portion and a curved portion, a curvature of the flexible patterning device substantially corresponding to a curvature of the closed loop trajectory; a substrate table constructed to hold a substrate; wherein the rotary drive comprises a pulley assembly configured to: engage, during use, the flexible patterning device, and maintain, during use, a portion of the flexible patterning device that is situated along the straight portion of the trajectory substantially flat, the substantially flat portion of the patterning device being configured to impart the radiation beam with a pattern in its cross-section to form a patterned radiation beam, and; a projection system configured to project the patterned radiation beam onto a target portion of the substrate.
Abstract:
An exposure apparatus is equipped with two stages (WST1, WST2) that are movable independently from each other and each have a table (WTB) at which a grating (RG) is provided at a position under a surface where a wafer (W) is mounted, and a measurement stage (MST)that is movable independently from the two stages and performs a measurement related to exposure based on a light-receiving result of the energy beam received via an optical system. In an exposure station (200) and a measurement station (300), a first measurement system and a second measurement system are respectively provided which measure the position of the table that the stage has, by irradiating the grating of the stage from below with a measurement beam.
Abstract:
A substrate holder (100) for a lithographic apparatus has a main body having a thin-film stack (110) provided on a surface thereof. The thin-film stack forms an electronic or electric component such as an electrode, a sensor, a heater, a transistor or a logic device, and has a top isolation layer. A plurality of burls (106) to support a substrate (W) are formed on the thin-film stack or in apertures of the thin-film stack.
Abstract:
A lithographic apparatus has a support that is provided with burls for holding an object. The support has been fabricated with a lithographic manufacturing method, e.g., a MEMS-technology, so as to create burls whose orientations or positions are individually electrically controllable.

The apparatus comprises a body (680) provided with a first set of fingers (684a, b) for carrying an undamped substrate and a second set of fingers (685a, b) for carrying a substrate support structure (403), and the first set of fingers is located below the second set of fingers, and fingers of the first set of fingers have a different shape than the fingers of the second set of fingers.
Abstract:
A substrate support is provided for a lithographic apparatus. The support comprises a substrate table constructed to hold a substrate and a chuck for the substrate table. In operation, the substrate table is supported by the chuck and clamped thereto. The substrate support comprises a first set of burls on a surface of the support block for abutting against the substrate table during the clamping and a second set of burls on a surface of the substrate table for abutting against the support block during the clamping.
