Patent number: 9547235Abstract: An imprint lithography method is disclosed for forming a patterned layer from an imprintable liquid medium on a substrate by means of an imprint template having a patterned surface. The method involves contacting the patterned surface and imprintable liquid medium together for a filling period. Light emergent (e.g., scattered or reflected) from an interface between the medium and the patterned surface is collected and measured during the filling period to obtain data concerning one or more voids at the interface, and an estimated end time for the filling period is derived from a relationship between the data and time. The method may allow subsequent process steps to be undertaken more rapidly, with reduced risk of defects arising from remnants of unfilled voids. An imprint lithography apparatus and component for putting the method into effect are also disclosed.Type: GrantFiled: October 5, 2010Date of Patent: January 17, 2017Assignee: ASML NETHERLANDS B.V.Inventors: Jeroen Herman Lammers, Sander Frederik Wuister, Yvonne Wendela Kruijt-Stegeman, Roelof Koole

Patent number: 9513553Abstract: A method is disclosed to form a patterned epitaxy template, on a substrate, to direct self-assembly of block copolymer for device lithography. A resist layer on a substrate is selectively exposed with actinic (e.g. UV or DUV) radiation by photolithography to provide exposed portions in a regular lattice pattern of touching or overlapping shapes arranged to leave unexposed resist portions between the shapes. Exposed or unexposed resist is removed with remaining resist portions providing the basis for a patterned epitaxy template for the orientation of the self-assemblable block copolymer as a hexagonal or square array. The method allows for simple, direct UV lithography to form patterned epitaxy templates with sub-resolution features.Type: GrantFiled: March 19, 2013Date of Patent: December 6, 2016Assignee: ASML NETHERLANDS B.V.Inventors: Sander Frederik Wuister, Vadim Yevgenyevich Banine, Jozef Maria Finders, Roelof Koole, Emiel Peeters, Harmeet Singh
