Patent number: 6987559Abstract: Devices are disclosed for placement between first and second masses for attenuating transmission of motions from one of the masses to the other. A general embodiment of such a device includes a fluid isolator and a lateral fluid bearing situated along a support axis. The fluid isolator includes a housing defining an isolator chamber pressurized with a gas at pressure Pisol. The fluid isolator is situated such that motion of the masses relative to each other along the support axis is at the fluid isolator, and lateral motion is at the lateral fluid bearing. The lateral fluid bearing includes first and second bearing surfaces that are transverse to the support axis. At least one such surface defines three channels: pressure channel, atmospheric pressure channel, and vacuum channel. In order from the isolator chamber, the pressure channel (at pressure PXYbearing?Pisol) is first, the atmospheric pressure channel (at pressure Patm) is second, and the vacuum channel (at pressure Pvac) is third.Type: GrantFiled: October 15, 2002Date of Patent: January 17, 2006Assignee: Nikon CorporationInventors: Alton H. Phillips, Hideaki Sakamoto, Michael B. Binnard

Patent number: 6710850Abstract: A reticle stage moves while holding the reticle. A stage controller detects the acceleration of the reticle stage based on the results of detection of an laser interference system. A main control system controls movement of the reticle stage so that the acceleration detected by the reticle stage becomes within a predetermined range of acceleration of the reticle stage where offset will not occur in the reticle. An image of the pattern formed on the reticle is transferred to a wafer through a projection optical system while synchronously moving the reticle and the wafer.Type: GrantFiled: December 20, 2001Date of Patent: March 23, 2004Assignee: Nikon CorporationInventors: Atsushi Yamaguchi, Hideaki Sakamoto, Yasuhiro Honda

Patent number: 6327024Abstract: A vibration isolation apparatus for preventing shaking and vibration of a stage of an exposure apparatus or the like uses a vibration isolation mount formed of a spring buffer system employing a spring member and a fluid buffer system employing a viscous fluid as a vibration isolation base which is disposed between a base member on which an exposure unit is mounted and an installation surface on which the base member is installed so as to support the base member. The coefficient of viscous drag of the viscous fluid is varied to vary a damping coefficient which depends on the coefficient of viscous drag thereby to vary rigidity of the vibration isolation mount, whereby vibration transmitted from an external source and vibration associated with a stage movement are damped.Type: GrantFiled: April 10, 2000Date of Patent: December 4, 2001Assignee: Nikon CorporationInventors: Yutaka Hayashi, Hideaki Sakamoto

Patent number: 5931441Abstract: A method is provided for suppressing vibration of a body supported by an anti-vibration mount having a predetermined damping coefficient and a predetermined spring constant. The method includes the steps of applying a predetermined force to the body, detecting motion of the body generated in response to the predetermined force, and deriving a mechanical constant of the body from the damping coefficient and the spring constant of the anti-vibration mount and the detected motion of the body generated in response to the predetermined force. The method further includes the steps of monitoring the vibration of the body, and exerting a controlling force to the body in accordance with the monitored vibration of the body and the derived mechanical constant of the body to suppress the vibration of the body.Type: GrantFiled: February 27, 1997Date of Patent: August 3, 1999Assignee: Nikon CorporationInventor: Hideaki Sakamoto

Patent number: 5108296Abstract: A connector for mounting and grounding electrical components to an underlyuing electrically conductive support structure by a mounting screw includes an electrically insulating mounting block which defines at least one mounting hole. A bent, electrically conductive bus bar having upper and lower legs is operatively associated with the mounting block such that a terminal end portion of the lower leg extends from the mounting block so as to contact the mounting screw when the connector is mounted to the support structure. Thus, grounding of the bus bar to the support structure occurs through the mounting screw. A reinforcement ring may be provided for the mounting hole which is positionally retained therewithin by various structures. Thus, reliable mounting and grounding of an electrical component may be achieved by the connectors of this invention, while minimizing the risk that excessive tightening of the mounting screw will result in breakage of the mounting block in the vicinity of the mounting hole.Type: GrantFiled: July 26, 1991Date of Patent: April 28, 1992Assignee: Daiichi Denso Buhin Co., Ltd.Inventors: Tsunesuke Takano, Kouichi Sinzawa, Hideaki Sakamoto

Patent number: 4999669Abstract: An exposure apparatus for forming a pattern of a mask on a photo-sensitive substrate comprises an X-Y stage, a Z-stage supported on the X-Y stage, and a levelling stage that supports the photo-sensitive substrate. The levelling stage is supported on the Z-stage by a plurality of levelling devices that define a levelling reference plane, and that are operated in unison to change the level of the levelling stage relative to the Z-stage and relative to an exposure reference plane that is parallel to the levelling reference plane. The levelling devices are also operated individually to change the inclination of the photo-sensitive substrate relative to the levelling reference plane and relative to the exposure reference plane. A focus detector controls the movement of the Z-stage and the in-unison movement of the levelling devices. An inclination detector controls the individual operation of the levelling devices.Type: GrantFiled: July 12, 1989Date of Patent: March 12, 1991Assignee: Nikon CorporationInventors: Hideaki Sakamoto, Kesayoshi Amano
