Abstract:
PROBLEM TO BE SOLVED: To provide immersion liquid containing one or more additives which further prevent the problem of a stain. SOLUTION: The immersion liquid contains an ion forming component containing acid or base having, for example, comparatively high vapor pressure. Lithographing method and system using this immersion liquid is also provided. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To reduce or dissolve temperature changes of liquid immersion solution being supplied to a lithographic apparatus. SOLUTION: A fluid supply system for a lithographic apparatus includes a controller configured to vary fluid flow rate to a first component from a fluid source while maintaining total flow resistance to fluid downstream of the fluid source substantially constant.

Abstract:
PROBLEM TO BE SOLVED: To provide a system which reduces pollution in an immersion lithographic apparatus, and reduces an interruption time for cleaning the immersion lithographic apparatus if not eliminated. SOLUTION: A cleaner (for instance, an active cleaning agent) is added to immersion liquid in order to clean and/or prevent accumulation of pollution during exposure of a substrate to clean the immersion lithographic apparatus. For the cleaner, a surface-active agent, a cleaning agent, soap, an acid, an alkali, a solvent (nonpolar organic solvent, polar organic solvent or the like), another optional cleaning agent appropriate for a lithographic apparatus or the like is used. The cleaning agent may be present at a concentration
Abstract:
PROBLEM TO BE SOLVED: To provide a system for detecting a flow in a two-phase flow; and to provide a system for detecting a ratio of gas to liquid in a two-phase flow.SOLUTION: The lithographic device including a duct for running a two-phase flow therein is disclosed. A flow divider for dividing a two-phase flow into a gas flow and a liquid flow is provided. A flowmeter measures a flow rate of a fluid in a gas flow or liquid flow.
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus by which two-phase flow can be stabilized and/or at least substantially separated into liquid and gas flows, and desirably substantially minimized. SOLUTION: An immersion lithographic apparatus is described in which a two-phase flow is separated into liquid-rich and gas-rich flows by causing the liquid-rich flow to preferentially flow along a surface.

Abstract:
PROBLEM TO BE SOLVED: To supply a cleaning liquid, having a rate of a base liquid and an emulsified component within a desirable work region, to an immersion system to be cleaned. SOLUTION: A cleaning liquid supply apparatus is configured to supply an emulsified cleaning fluid to an immersion lithographic apparatus. The apparatus includes a mixer configured to mix an additive fluid from an additive fluid supply section and an immersion liquid from an immersion supply section so as to prepare the emulsified cleaning fluid, a sensor system configured to sense physical characteristics of the emulsified cleaning fluid, and a controller connected to the sensor and mixer. The controller controls the supply of the additive fluid from the additive fluid supply section to the mixer and physical characteristics of the emulsified cleaning fluid.

Abstract:
PROBLEM TO BE SOLVED: To adjust a conventional lithography equipment to an environment of immersion. SOLUTION: In the lithography projection equipment, a liquid supply system and an object W on a substrate table WT are arranged to prevent a high-speed immersion liquid from flowing onto a sensor S.
