Abstract:
PROBLEM TO BE SOLVED: To provide a lithography apparatus, a method of manufacturing a device, and a device manufactured by the same. SOLUTION: The lithography apparatus 1 configured to transfer a pattern from a pattern forming structure to a substrate has a substrate holder 4 configured to hold the substrate, and a substrate thermoregulator configured to adjust the temperature of the substrate before movement and during movement so that it may be made substantially in agreement with the temperature of the substrate holder 4.

Abstract:
PROBLEM TO BE SOLVED: To solve such problems that: degraded dynamic behaviors may prolong a stable time (i.e. the desired time for bringing the position of an object table into a desired error bandwidth); larger forces are desirably provided in order to obtain the desired acceleration of a patterning device or a substrate; and the positioning accuracy of the object is affected as a result of that. SOLUTION: There is described a stage apparatus for displacing an object having a substantially flat surface. The stage apparatus is provided with an object table for supporting the object and a positioning device for displacing the object table in a first direction. The stage apparatus is further provided with a clamping device for clamping the object to the object table by a first clamping force that is controlled by an electronic control unit on the basis of the condition of the object.

Abstract:
A method for compensating for an exposure error in an exposure process of a lithographic apparatus that comprises a substrate table, the method comprising: obtaining a dose measurement indicative of a dose of IR radiation that reaches substrate level, wherein the dose measurement can be used to calculate an amount of IR radiation absorbed by an object in the lithographic apparatus during an exposure process; and using the dose measurement to control the exposure process so as to compensate for an exposure error associated with the IR radiation absorbed by the object during the exposure process.
Abstract:
A lithographic apparatus has an assembly to exchange optical elements in a pupil plane of its projection system. The optical elements may be pupil filters and may conform to the physical dimensions specified for a reticle standard, e.g. having sides substantially equal to 5, 6 or 9 inches.
Abstract:
A lithographic apparatus (1) arranged to transfer a pattern from a patterning structure (MA) onto a substrate (W) is disclosed that includes a substrate holder configured to hold a substrate and a substrate temperature conditioner configured to condition a temperature of the substrate prior to, during, or both, a transfer of the substrate to the substrate holder to substantially match a temperature of the substrate holder. Besides, there is provided a lithographic apparatus arranged to transfer a pattern from a patterning structure onto a substrate, comprising: a first patterning structure holder (MT) configured to hold a patterning structure (MA); a patterning structure temperature conditioner (140) configured to condition a temperature of the patterning structure prior to a transfer of the patterning structure to the patterning structure holder, wherein the patterning structure temperature conditioner is provided with a second patterning structure holder (113); and at least one system (125,126) to thermally condition the first and second patterning structure holder to substantially the same temperature.
