A flow, desirably a radial flow, is induced in the liquid. | 11-20-2008 |
| 20090015804 | Cleaning device and a lithographic apparatus cleaning method - A cleaning tool to clean a surface of a component of a lithographic apparatus is disclosed. The cleaning tool includes a sonic transducer, a liquid supply device configured to provide liquid to a reservoir between the surface to be cleaned and the sonic transducer, and a liquid outlet configured to remove liquid provided by the liquid supply device, the cleaning tool constructed and arranged such that, in use, liquid flows into the outlet under the influence of gravity. | 01-15-2009 |
| 20090015805 | Cleaning device, a lithographic apparatus and a lithographic apparatus cleaning method - A cleaning tool to clean a surface of a liquid confinement system of an immersion lithographic apparatus is disclosed, the liquid confinement system having an aperture to allow passage of a beam of radiation therethrough of an immersion lithographic apparatus. The cleaning tool includes a sonic transducer, a reservoir configured to hold liquid between the sonic transducer and the surface to be cleaned, and a barrier positioned in the reservoir under the aperture to form, in use, a shield to sonic waves. | 01-15-2009 |
| 20110069290 | CLEANING DEVICE, A LITHOGRAPHIC APPARATUS AND A LITHOGRAPHIC APPARATUS CLEANING METHOD - A cleaning tool to clean a surface of a liquid confinement system of an immersion lithographic apparatus is disclosed, the liquid confinement system having an aperture to allow passage of a beam of radiation therethrough of an immersion lithographic apparatus. The cleaning tool includes a sonic transducer, a reservoir configured to hold liquid between the sonic transducer and the surface to be cleaned, and a barrier positioned in the reservoir under the aperture to form, in use, a shield to sonic waves. | 03-24-2011 |
| 20110080567 | LITHOGRAPHIC APPARATUS AND A METHOD OF OPERATING THE APPARATUS - 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. | 04-07-2011 |
| 20110128516 | LITHOGRAPHIC APPARATUS AND SURFACE CLEANING METHOD - An apparatus and method for cleaning a contaminated surface of a lithographic apparatus are provided. A liquid confinement structure comprises at least two openings used to supply and extract liquid to a gap below the structure. The direction of flow between the openings can be switched. Liquid may be supplied to the gap radially outward of an opening adapted for dual flow. Supply and extraction lines to respectively supply liquid to and extract liquid from the liquid confinement structure have an inner surface that is resistant to corrosion by an organic liquid. A corrosive cleaning fluid can be used to clean photo resist contamination. | 06-02-2011 |
