Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for cleaning a component of a lithographic apparatus in situ. SOLUTION: In a low-pressure environment, by applying a voltage between a tool tip in close proximity to a surface and that surface, contaminants on the surface are attracted and adhered to a tool. Also, a laser is used and each component of a lithographic projection apparatus is cleaned in situ. COPYRIGHT: (C)2003,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid immersion lithographic apparatus and a device manufacturing method, in which disturbance force transmitted to a substrate is reduced. SOLUTION: This is an apparatus for liquid immersion lithography, in which a compensation controller controls actuators to apply forces to the substrate equal in magnitude and opposite in direction to forces which are applied to the substrate by a liquid supply system which supplies liquid between a final element of a projection system and the substrate.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of effectively compensating for a positional shift including a tilt between a substrate and a supporting structure and a vertical displacement when moving the substrate in a lithographic projection apparatus using the supporting structure. SOLUTION: By providing compliant parts (14, 26) in the supporting structure for holding and moving a substrate (W), for example, a supporting frame (18) of a robot arm (10) adaptable to the tilt and/or the vertical displacement. Clamps (20, 22, 24) that the supporting frame (18) comprises may be a Johnson-Raybeck effect type clamp that requires a stringent positional precision, and the cleaning of the inside of the projection apparatus is carried out by using only one substrate.

Abstract:
PROBLEM TO BE SOLVED: To provide a method capable of effectively compensating an inclination between a substrate and a support structure or a misregistration including a displacement in the vertical direction when the substrate is moved by the support structure in a lithographic projection apparatus. SOLUTION: By providing a support structure for holding and moving a substrate (W), for example, flexible sections (14, 26) in a support frame (18) of a robot arm (10), it can be adapted to the tilt and/or a displacement in the vertical direction. Clamps (20, 22, 24) provided on the support frame (18) may be a Johnson-Raybeck effect type clamp, which requires the severe position accuracy, and can perform a cleaning treatment in a projection apparatus by only one substrate.

Abstract:
PROBLEM TO BE SOLVED: To provide a modified lithographic projection apparatus with an effective arrangement for reducing a harmful effect of vibration on the lens. SOLUTION: The lithographic projection apparatus comprises a detection device 210 for detecting a relative movement between a first part and a second part of a silent region 13 and for generating at least one movement signal which represents the relative movement, an action device 220 which reacts to at least one control signal for applying a force on the silent region, and a control device 21 which reduces the relative movement between the first part and the second part by generating at least one control signal reacting to at least one movement signal.

In a low-pressure environment, a voltage is applied between a tool tip in close proximity to a surface and that surface. Contaminants on the surface are attracted and adhere to the tool.
Abstract:
A lithographic apparatus for immersion lithography is described in which a compensation controller (30) controls actuators (45) to apply forces (F 1 ,F 2 ) to the substrate (W) equal in magnitude and opposite in direction to forces which are applied to the substrate by the liquid supply system which supplies liquid between the final element of the projection system (PL) and the substrate (W).
