Publication number: 20120153543Abstract: A lithography apparatus comprises a projection system arranged to transfer a pattern from a patterning device onto a substrate, a carrier, and a drive system for moving the carrier relative to the projection system in a plane defined by reference to orthogonal axes X and Y. The drive system comprises a shuttle moving parallel to the Y-axis, a shuttle connector connecting the shuttle to the carrier, the shuttle connector allowing movement of the carrier in a direction parallel to the X-axis relative to the shuttle, and a shuttle driver for driving movement of the shuttle parallel to the Y-axis. The shuttle is located to one side of the carrier in a direction parallel to the X-axis and it is desirable if only one of the shuttle is connected to the carrier.Type: ApplicationFiled: November 15, 2011Publication date: June 21, 2012Applicant: ASML Netherlands B.V.Inventors: Johannes Petrus Martinus Bernardus Vermeulen, Antonius Franciscus Johannes De Groot, Theodorus Petrus Maria Cadee, Jeroen De Boeij

Patent number: 8202463Abstract: An imprint method includes contacting a template on a first substrate. The template includes a pattern to be transferred on the first substrate. The first substrate includes a first semiconductor substrate, and a first light curable resin coated on the first semiconductor substrate. The method further includes separating the template from the first substrate, and removing particles adhered on the template. The particle removal includes: pressing the template on an adhesive member which is distinct from the first substrate. The adhesive member includes a dummy substrate, a particle removing film formed on the dummy substrate and configured to remove the particles, and a second light curable resin coated on the particle removing film. The second light curable resin is thicker than the first light curable resin.Type: GrantFiled: April 20, 2009Date of Patent: June 19, 2012Assignee: Kabushiki Kaisha ToshibaInventors: Ikuo Yoneda, Tetsuro Nakasugi, Shinji Mikami

Publication number: 20120148701Abstract: The present invention generally relates to an optical system that is able to reliably deliver a uniform amount of energy across an anneal region contained on a surface of a substrate. The optical system is adapted to deliver, or project, a uniform amount of energy having a desired two-dimensional shape on a desired region on the surface of the substrate. Typically, the anneal regions may be square or rectangular in shape. Generally, the optical system and methods of the present invention are used to preferentially anneal one or more regions found within the anneal regions by delivering enough energy to cause the one or more regions to re-melt and solidify.Type: ApplicationFiled: February 21, 2012Publication date: June 14, 2012Applicant: APPLIED MATERIALS, INC.Inventors: Bruce E. Adams, Samuel C. Howells, Dean Jennings, Jiping Li, Timothy N. Thomas, Stephen Moffatt

Publication number: 20120139166Abstract: An apparatus for making a three-dimensional object includes a table, a powdery layer-former that forms a powdery layer on the table, and an optical beam-irradiator that irradiates an optical beam on a predetermined region of the powdery layer to sinter the predetermined region of the powdery layer. A chamber for accommodating the table and the powdery layer-former and a lid for opening and closing an opening defined in the chamber at a location immediately above an optical beam-irradiating range are provided. The three-dimensional object is taken out from the chamber through the opening upon completion of the sintering, and the optical beam-irradiator is disposed at a position deviated from immediately above the optical beam-irradiating range to obliquely irradiate the optical beam on the powdery layer.Type: ApplicationFiled: October 17, 2011Publication date: June 7, 2012Applicant: PANASONIC ELECTRIC WORKS CO., LTD.Inventors: Satoshi ABE, Isao FUWA, Norio YOSHIDA, Yoshikazu HIGASHI, Hirohiko TOGEYAMA, Masataka TAKENAMI, Takashi SHIMIZU, Shushi UENAGA
