Abstract:
PROBLEM TO BE SOLVED: To disclose a liquid immersion lithographic device for immersing a substrate in a lithography projection device in a liquid having a relatively high refractive index such as water so as to fill a space between the final element of a projection system and the substrate. SOLUTION: In the liquid immersion lithographic device, a liquid removing device is configured so as to remove the liquid from the substrate through a plurality of slender slots disposed along a line and also having an angle to the line, for example during exposure. The liquid removing device can act as a meniscus-fixed fixing device in a liquid immersion hood or used in a drying device for removing a liquid droplet from the substrate.

Abstract:
PROBLEM TO BE SOLVED: To provide a liquid immersion lithographic apparatus in which a member is disposed over the surfaces of a substrate and a substrate table. SOLUTION: An immersion liquid is provided to a space between a substrate table, a substrate, and a member. In this embodiment, a radiation beam can pass through a plate. In the other embodiment, the member has a radiation beam pass-through hole. COPYRIGHT: (C)2009,JPO&INPIT
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:
A lithographic projection apparatus includes conduits which supply utilities to components in a vacuum chamber such as object tables and/or associated motors and/or sensors. The conduits are shielded from exposure to the vacuum by conduit conducts having at least the same number of degrees of freedom as their associated object table.
Abstract:
A method of and apparatus for maintaining a machine part arranged in an interior space of a machine, where the interior space is kept at a first pressure and is separated from an environment having a second pressure via a load lock. The method includes transporting a machine part via the load lock out of the interior space and transporting via the load lock into the interior space one of the maintained machine part and a separate replacement machine part.
Abstract:
The present invention relates to a lithographic projection apparatus with a supporting structure to support and move an object, like a substrate (W). The supporting structure maybe a robot (8). The robot (8) has a robot arm (10) with a support frame (18) for supporting, e.g. the substrate (W). The support frame (18) has one or more clamps (20, 22, 24) for holding the object (W) during movement. The robot arm comprises one or more compliant parts (14; 26; 28). The clamp may be a Johnson-Raybeck effect type clamp with an oxidized upper surface. For better de-clamping, a RF AC decaying de-clamping voltage may be provided to the clamp. The apparatus maybe cleaned with one single substrate only.

Abstract:
An immersion lithographic apparatus is described in which a liquid removal device is arranged to remove liquid from the substrate, e.g. during exposures, through a plurality of elongate slots arranged along a line and angled to that line. The liquid removal device may act as a meniscus pinning device in an immersion hood or may be used in a drying device to remove a droplet from the substrate.
