Abstract:
A transport box for transporting a lithographic patterning device and a lithographic apparatus adapted to cooperate with the transport box are presented. The transport box is provided with a container part having an inner space with a storing position for storing the patterning device and an opening for the transfer of the patterning device. The box also includes a closure part for closing the opening, and a channel system for evacuating and/or feeding gasses from/to the inner space the box.
Abstract:
A lithographic projection apparatus is disclosed in which a space between the projection system and the substrate is filled with a liquid. An edge seal member at least partly surrounds the substrate or other object on a substrate table to prevent liquid loss when edge portions of the substrate or other object are, for example, imaged or illuminated.
Abstract:
According to an embodiment, a box for transporting a lithographic patterning device is arranged to cooperate with a lithographic apparatus. The transport box may be provided with a container part having an inner space with a storing position for storing the patterning device and an opening for the transfer of the patterning device. Prior to transfer of the patterning device from the inner space to the apparatus, the inner space is pressurized. The box may also comprise a closure part for closing the opening, and/or a channel system for evacuating and/or feeding gasses from/to the inner space of the box. Other embodiments include a lithographic apparatus comprising and/or configured to cooperate with such a box.
Abstract:
In a lithographic projection apparatus, a measuring system configured to measure the position of the projection system relative to a reference frame includes sensors rigidly mounted in relation to counterpart sensors of a measuring system measuring the substrate table position. An angular encoder which sends light from a target down two optical paths having opposite sensitivities to tilt is used to measure rotation of the projection system about its optical axis.
Abstract:
A lithographic projection apparatus is disclosed for use with an immersion liquid positioned between the projection system and a substrate. Several methods and mechanism are disclosed to protect components of the projection system, substrate table and a liquid confinement system. These include providing a protective coating on a final element of the projection system as well as providing one or more sacrificial bodies upstream of the components. A two component final optical element of CaF2 is also disclosed.
Abstract:
A lithographic projection apparatus is disclosed in which a space between the projection system and the substrate is filled with a liquid. An edge seal member at least partly surrounds the substrate or other object on a substrate table to prevent liquid loss when edge portions of the substrate or other object are, for example, imaged or illuminated. A lithographic projection apparatus includes a support structure configured to hold a patterning device, the patterning device configured to pattern a beam of radiation according to a desired pattern; a substrate table configured to hold a substrate; a projection system configured to project the patterned beam onto a target portion of the substrate; a liquid supply system configured to provide liquid to a space between the projection system and the substrate; and a shutter configured to isolate the space from the substrate or a space to be occupied by a substrate.
Abstract:
A map of the surface of a substrate is generated at a measurement station. The substrate is then moved to where a space between a projection lens and the substrate is filled with a liquid. The substrate is then aligned using, for example, a transmission image sensor and, using the previous mapping, the substrate can be accurately exposed. Thus the mapping does not take place in a liquid environment.

Abstract:
The invention relates to a method of manufacturing an electrostatic clamp configured to electrostatically clamp an article to an article support in a lithographic apparatus. The method includes providing a first layer of material, etching a recess in the first layer of material, and disposing an electrode in the recess of the first layer of material.
