Patent number: 8982317Abstract: In order to effectively transfer heat from inner layers of an actuator coil to an area external to the coil, heat transfer elements, located proximate to the actuator coil, can be used. In an embodiment, a heat transfer apparatus for the actuator coil can include one or more heat transfer elements located proximate to one or more layers or one or more windings of the actuator coil and a cooling surface located proximate to the one or more heat transfer elements and to the actuator coil. In this configuration, the heat transfer apparatus can transfer heat from inner layers of the actuator coil to the cooling surface, which in turn transfers the heat to an area external to the actuator coil.Type: GrantFiled: July 31, 2009Date of Patent: March 17, 2015Assignee: ASML Holding N.V.Inventors: Roberto B.

Patent number: 8879045Abstract: A method utilizes a dynamically controllable optical element that receives an electrical field, which changes an index of refraction in at least one direction within the optical element. The change in index of refraction imparts a change to a beam of radiation passing through the optical element. The electric field is controlled by a feedback/control signal from a feedback system that includes a detector positioned proximate an image plane in the system. The optical element can be positioned in various places within the system depending on what light characteristics need to be adjusted, for example after an illumination system or after a light patterning system. In this manner, the optical element, under control of the dynamic electric field, can dynamically change its propagation characteristics to dynamically change either a beam of illumination from the illumination system or a patterned beam of radiation from the patterning system, such that they exhibit desired light characteristics.Type: GrantFiled: December 9, 2010Date of Patent: November 4, 2014Assignee: ASML Holding N.V.Inventors: James G. Tsacoyeanes, Pradeep K. Govil

Patent number: 7372614Abstract: A deformable optical device includes a reflection device having a first reflecting surface and a second surface, an actuator (e.g., an integrated circuit piezoelectric actuator) having a support device and moveable extensions extending therefrom, which are coupled to the second surface, and electrodes coupled to corresponding ones of the extensions. Wavefront aberrations are detected and used to generate a control signal. The extensions are moved based on the control signal. The movement deforms the reflecting surface to correct the aberrations in the wavefront.Type: GrantFiled: October 6, 2005Date of Patent: May 13, 2008Assignee: ASML Holding N.V.Inventors: Pradeep K.

Patent number: 7265815Abstract: A method and system are used to control a characteristic of a beam. The system comprises an illumination system, at least one optical element, a fluid source, and a pressure and/or fluid concentration controller. The illumination system produces a beam of radiation. The at least one optical element has at least one fluid path therethrough through which the beam passes and is capable of changing a characteristic of one or more portions of the beam. The fluid source supplies fluid to the at least one fluid path. The pressure and/or fluid concentration controller controls pressure and/or fluid concentration of the fluid to change the characteristic of the beam, which is positioned between the fluid source and the optical element.Type: GrantFiled: May 19, 2005Date of Patent: September 4, 2007Assignee: ASML Holding N.V.Inventor: Pradeep K.
