Patent number: 10488759Abstract: An immersion lithographic apparatus is provided with a liquid confinement structure which defines at least in part a space configured to contain liquid between the projection system and the substrate. In order to reduce the crossing of the edge of the substrate which is being imaged (which can lead to inclusion of bubbles in the immersion liquid), the cross-sectional area of the space in a plane parallel to the substrate is made as small as possible. The smallest theoretical size is the size of the target portion which is imaged by the projection system. In an embodiment, the shape of a final element of the projection system is also changed to have a similar size and/or shape in a cross-section parallel to the substrate to that of the target portion.Type: GrantFiled: April 7, 2017Date of Patent: November 26, 2019Assignee: ASML Netherlands B.V.Inventors: Bob Streefkerk, Sjoerd Nicolaas Lambertus Donders, Roelof Frederik De Graaf, Christiaan Alexander Hoogendam, Hans Jansen, Martinus Hendrikus Antonius Leenders, Paulus Martinus Maria Liebregts, Jeroen Johannes Sophia Maria Mertens, Jan-Gerard Cornelis Van Der Toorn, Michel Riepen

Patent number: 10466595Abstract: In a lithographic apparatus, a localized area of the substrate surface under a projection system is immersed in liquid. The height of a liquid supply system above the surface of the substrate can be varied using actuators. A control system uses feedforward or feedback control with input of the surface height of the substrate to maintain the liquid supply system at a predetermined height above the surface of the substrate.Type: GrantFiled: October 23, 2017Date of Patent: November 5, 2019Assignee: ASML Netherlands B.V.Inventors: Bob Streefkerk, Johannes Jacobus Matheus Baselmans, Henrikus Herman Marie Cox, Antonius Theodorus Anna Maria Derksen, Sjoerd Nicolaas Lambertus Donders, Christiaan Alexander Hoogendam, Joeri Lof, Erik Roelof Loopstra, Jeroen Johannes Sophia Maria Mertens, Frits Van Der Meulen, Johannes Catharinus Hubertus Mulkens, Gerardus Petrus Matthijs Van Nunen, Klaus Simon, Bernardus Antonius Slaghekke, Alexander Straaijer, Jan-Gerard Cornelis Van Der Toorn, Martijn Houkes
