| 20090014030 | Substrates and methods of using those substrates - A method of removing contamination from an apparatus used in lithography is disclosed. The method includes loading a substrate into the apparatus, the substrate comprising a rigid support layer and a deformable layer provided on the rigid support layer, bringing the deformable layer of the substrate into contact with a surface of the apparatus from which contamination is to be removed, introducing relative movement between the deformable layer and the surface of the apparatus from which contamination is to be removed to dislodge contamination from the surface for removal, and removing the dislodged contamination. Other aspects of the invention are also described and claimed. | 01-15-2009 |
| 20090025753 | Lithographic Apparatus And Contamination Removal Or Prevention Method - A lithographic apparatus is disclosed having an in situ ozonizer, which is used to produce ozone gas, for example, by UV irradiation of an oxygen-containing gas. The thus produced ozone is dissolved in ultra-pure water by contacting the ozone with the ultra-pure water through a permeable membrane. | 01-29-2009 |
| 20090027635 | Lithographic Apparatus and Contamination Removal or Prevention Method - 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). | 01-29-2009 |
| 20090174871 | Lithographic apparatus and method of cleaning a surface of an immersion lithographic apparatus - A method of cleaning a lithography apparatus using an aerosol spray is described. The spray from the aerosol is contained in a space. | 07-09-2009 |
| 20100097587 | LITHOGRAPHIC APPARATUS AND A METHOD OF REMOVING CONTAMINATION - A lithographic apparatus includes a fluid supply system configured to provide a cleaning fluid to a surface to be cleaned. The cleaning fluid includes from 25 to 98.99 wt % water; from 1 to 74.99 wt % solvent selected from one or more glycol ethers, esters, alcohols and ketones; and from 0.01 to 5 wt % surfactant. | 04-22-2010 |
| 20110188013 | LITHOGRAPHIC APPARATUS AND CONTAMINATION REMOVAL OR PREVENTION METHOD - 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). | 08-04-2011 |
| 20110233175 | PICK-AND-PLACE MACHINE - A pick-and-place machine, comprising: a pick station; a place station; a pick/place head for transporting a die from the pick station along a transport path to the place station; wherein the machine further comprises a die-face processing means, comprising an inspection unit and/or a cleaning unit, operable to process a face of the die on the transport path. | 09-29-2011 |
