Patent number: 9482966Abstract: A lithographic projection apparatus is disclosed in which a space between the projection system and the substrate is filled with a liquid. An edge seal member at least partly surrounds the substrate or other object on a substrate table to prevent liquid loss when edge portions of the substrate or other object are, for example, imaged or illuminated. A lithographic projection apparatus includes a support structure configured to hold a patterning device, the patterning device configured to pattern a beam of radiation according to a desired pattern; a substrate table configured to hold a substrate; a projection system configured to project the patterned beam onto a target portion of the substrate; a liquid supply system configured to provide liquid to a space between the projection system and the substrate; and a shutter configured to isolate the space from the substrate or a space to be occupied by a substrate.Type: GrantFiled: September 13, 2012Date of Patent: November 1, 2016Assignee: ASML NETHERLANDS B.V.Inventors: Joeri Lof, Erik Theodorus Maria Bijlaart, Sjoerd Nicolaas Lambertus Donders, Christiaan Alexander Hoogendam, Erik Roelof Loopstra, Hendricus Johannes Maria Meijer, Jeroen Johannes Sophia Maria Mertens, Johannes Catharinus Hubertus Mulkens, Roelof Aeilko Siebrand Ritsema, Timotheus Franciscus Sengers, Klaus Simon, Joannes Theodoor De Smit, Alexander Straaijer, Bob Streefkerk

Patent number: 9477160Abstract: 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: February 17, 2015Date of Patent: October 25, 2016Assignee: ASML NETHERLAND 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

Publication number: 20160062248Abstract: A map of the surface of a substrate is generated at a measurement station. The substrate is then moved to where a space between a projection lens and the substrate is filled with a liquid. The substrate is then aligned using, for example, a transmission image sensor and, using the previous mapping, the substrate can be accurately exposed. Thus the mapping does not take place in a liquid environment.Type: ApplicationFiled: November 10, 2015Publication date: March 3, 2016Applicant: ASML NETHERLANDS B.V.Inventors: Joeri LOF, Joannes Theodoor De Smit, Roelof Aeilko Siebrand Ritsema, Klaus Simon, Theodorus Marinus Modderman, Johannes Catharinus Hubertus Mulkens, Hendricus Johannes Maria Meijer, Erik Roelof Loopstra
