Patent number: 9539800Abstract: Substrates are aligned and then bonded to each other. A substrate bonding apparatus includes a deformer that deforms at least a first one of two substrates that are to be bonded to each other in order to correct misalignment between the two substrates, a holder that holds the deformed first substrate in the deformed state achieved by the deformer, a transporter that transports the holder from a position at which the deformed first substrate is held by the holder while the first substrate remains deformed, and a bonder that bonds the first substrate that has been transported by the transporter to the second substrate.Type: GrantFiled: October 25, 2013Date of Patent: January 10, 2017Assignee: NIKON CORPORATIONInventors: Yoshiaki Kito, Hiroshi Shirasu, Masahiro Yoshihashi, Daisuke Yuki, Kazuhiro Suzuki, Isao Sugaya

Patent number: 9240339Abstract: A substrate holder is reliably transported in a state of holding a substrate. There is provided a substrate holder for holding a substrate by means of electrostatic force generated by power supplied from an external source. The substrate holder is to be transported in a state of holding the substrate. The substrate holder includes a holder body that is to have the substrate placed thereon, and a connector terminal that is externally exposed through the holder body, where the connector terminal is attachable to and detachable from an external power supply terminal. There is also provided a substrate transport apparatus for transporting a substrate holder holding a substrate by means of electrostatic force generated by power supplied from an external source.Type: GrantFiled: October 10, 2013Date of Patent: January 19, 2016Assignee: NIKON CORPORATIONInventors: Hidehiro Maeda, Masahiro Yoshihashi

Patent number: 8932432Abstract: A substrate separating method includes: holding, in a predetermined position, a substrate sandwiched between a first holder and a second holder opposed to each other; and relatively moving the first holder and the second holder while the substrate is held in the predetermined position. In holding the substrate, the substrate may be held in the predetermined position by effecting a pressurizing force or a suction force onto the substrate. Also in holding the substrate, the substrate may be held in contact with one of the first holder and the second holder.Type: GrantFiled: August 24, 2012Date of Patent: January 13, 2015Assignee: Nikon CorporationInventors: Keiichi Tanaka, Masahiro Yoshihashi

Patent number: 6524003Abstract: A linear motion guiding apparatus comprises a guide rail provided with a ball running groove, and a movable block movably arranged along the guide rail through balls. The movable block is provided with a ball running counter-groove, a ball returning passage arranged away from the ball running counter-groove and direction changing passages for connecting these members. A resin-formed body for forming a ball circulation passage comprises a pair of ball passage forming portions, a returning passage forming portion and a pair of direction changing passage-inner guide forming portions. The resin-formed body is separately formed from a body of the movable block.Type: GrantFiled: July 18, 2001Date of Patent: February 25, 2003Assignee: THK Co., Ltd.Inventors: Hidekazu Michioka, Katsuya Iida, Masahiro Yoshihashi, Hiroaki Mochizuki, Tadashi Hirokawa
