摘要:
A system for cleaning a limited area of a top surface of a substrate table or an object positioned on a top surface of a substrate table is disclosed. The optical system used during normal imaging is adjusted to limit the cross-sectional area of a radiation beam to form a cleaning radiation beam which impinges on the limited area.
摘要:
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.
摘要:
An immersion lithographic projection apparatus having a megasonic transducer configured to clean a surface and a method of using megasonic waves through a liquid to clean a surface of an immersion lithographic projection apparatus are disclosed. A flow, desirably a radial flow, is induced in the liquid.
摘要:
An immersion lithographic apparatus is disclosed that includes a detector to measure a distance between a substrate support structure and/or a substrate and a fluid handling system and/or to detect when an item is present between the fluid handling system and a top surface of the substrate and/or substrate support structure. The detector may use information of an electrical property of the fluid provided by the fluid handling system to measure the distance. The detector may measure variation in resistance and/or in capacitance between an electrode of the fluid handling system and an electrode of the substrate and/or substrate support structure.
摘要:
An immersion lithographic apparatus comprising a surface which is curved such that a surface-tension drainage force acts in a direction on a film of immersion liquid on the surface.
摘要:
A cleaning liquid supply system is disclosed. The cleaning liquid supply system may supply an emulsified cleaning liquid to clean an immersion lithographic apparatus. A lithographic apparatus is also disclosed.
摘要:
A lithographic system includes an immersion type lithographic apparatus, which includes a support constructed and arranged to support a substrate, a projection system constructed and arranged to project a patterned beam of radiation onto a target portion of the substrate, a liquid confinement structure configured to at least partially fill a space between the projection system and at least one of the substrate and support with an immersion liquid, a liquid supply system arranged to provide the immersion liquid to the liquid confinement structure, and a cleaning liquid supply system arranged to provide a cleaning liquid to a surface of the lithographic apparatus that comes into contact with the immersion liquid. The system includes a switch to provide the cleaning liquid directly to the liquid confinement structure and to provide the immersion liquid indirectly to the liquid confinement structure via a liquid purification system.
摘要:
An immersion type lithographic apparatus includes an immersion system configured to at least partially fill an immersion space with an immersion liquid. The apparatus also includes an indicator configured to indicate whether a part of the immersion system should be cleaned and a cleaning liquid supply system configured to supply a cleaner to the part of the lithographic apparatus. The cleaner is at least one of a plurality of different cleaners. Each cleaner or combination of cleaners is configured to clean a different type and/or level of contamination in the part of the lithographic apparatus. The apparatus also includes a controller configured to control which of the plurality of cleaners is provided to the part of the lithographic apparatus, based on an indication received from the indicator.

A cleaning liquid supply system is disclosed. The cleaning liquid supply system may supply an emulsified cleaning liquid to clean an immersion lithographic apparatus. A lithographic apparatus is also disclosed.
摘要:
An immersion lithographic apparatus is cleaned by use of a cleaning liquid consisting essentially of ultra-pure water and (a) a mixture of hydrogen peroxide and ozone, or (b) hydrogen peroxide at a concentration of up to 5%, or (c) ozone at a concentration of up to 50 ppm, or (d) oxygen at concentration of up to 10 ppm, or (e) any combination selected from (a)-(d).
