| 20080259292 | Lithographic apparatus and device manufacturing method - A lithographic apparatus is disclosed including a liquid supply system configured to at least partly fill a space between the projection system and the substrate with a liquid, an outlet configured to remove a mixture of liquid and gas passing through a gap between a liquid confinement structure of the liquid supply system and the substrate, and an evacuation system configured to draw the mixture through the outlet, the evacuation system having a separator tank arranged to separate liquid from gas in the mixture and a separator tank pressure controller, connected to a non-liquid-filled region of the separator tank, configured to maintain a stable pressure within the non-liquid-filled region. | 10-23-2008 |
| 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 |
| 20090046261 | Lithographic apparatus and device manufacturing method - A manifold is provided between an outlet of a fluid supply system for an immersion lithographic apparatus and a separator. The manifold is provided with a pressure sensor which passes the measured pressure in the manifold to a mass flow controller. The mass flow controller controls a leak flow into the manifold based on the measured pressure in the manifold so as to maintain a desired pressure in the manifold. | 02-19-2009 |
| 20100110398 | METHODS RELATING TO IMMERSION LITHOGRAPHY AND AN IMMERSION LITHOGRAPHIC APPARATUS - A method of detecting particles in an immersion fluid of or from a lithographic apparatus. The method includes extracting a sample, using a vacuum system, from a single phase flow of the immersion fluid of or from a fluid handling structure in the lithographic apparatus. The method includes detecting particles in the sample, and initiating a signal if the detected particles are above a certain threshold. | 05-06-2010 |
| 20100321650 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - A lithographic apparatus is described having a liquid supply system configured to at least partly fill a space between a projection system of the lithographic apparatus and a substrate with liquid, a barrier member arranged to substantially contain the liquid within the space, and one or more elements to control and/or compensate for evaporation of liquid from the substrate. | 12-23-2010 |
| 20100328634 | LITHOGRAPHIC APPARATUS AND A METHOD OF OPERATING THE APPARATUS - A method of cleaning an immersion lithographic apparatus is disclosed in which a cleaner is added to immersion liquid for use during exposure of a substrate. The cleaner may be a combination of a soap and a solvent. The cleaner maybe present at a concentration of less than 300 ppb. | 12-30-2010 |
| 20110013159 | LITHOGRAPHIC APPARATUS AND A METHOD OF MEASURING FLOW RATE IN A TWO PHASE FLOW - A lithographic apparatus is disclosed that includes a conduit for two phase flow therethrough. A flow separator is provided to separate the two phase flow into a gas flow and a liquid flow. A flow meter measures the flow rate of fluid in the gas flow or the liquid flow. | 01-20-2011 |
| 20110074053 | HUMIDIFYING APPARATUS, LITHOGRAPHIC APPARATUS AND HUMIDIFYING METHOD - A humidifying apparatus is disclosed in which gas is provided to a first side of a membrane and liquid to a second side of the same membrane. The membrane is non-porous to the liquid but porous to vapour of the liquid and is liquidphilic to said liquid. | 03-31-2011 |
| 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 |
| 20110157568 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - A manifold is provided between an outlet of a fluid supply system for an immersion lithographic apparatus and a separator. The manifold is provided with a pressure sensor which passes the measured pressure in the manifold to a mass flow controller. The mass flow controller controls a leak flow into the manifold based on the measured pressure in the manifold so as to maintain a desired pressure in the manifold. | 06-30-2011 |
