Patent number: 8571704Abstract: A substrate transfer apparatus that reduces the quantity of sensors used to detect the position of a substrate so as to simplify the structure and lower costs. The substrate transfer apparatus transfers a substrate (S) between a core chamber (11) and a peripheral chamber (12 or 13). A transfer robot (15) is arranged in the core chamber. The transfer robot includes a hand (17) for carrying the substrate and is capable of extending/drawing and pivoting the hand. A sensor (19) detects an edge surface of the substrate. The sensor is arranged at a position that the edge surface of the substrate passes by when the hand is extended/drawn between the core chamber and the peripheral chamber and that the edge surface of the substrate passes by when the hand is pivoted in the core chamber.Type: GrantFiled: February 27, 2008Date of Patent: October 29, 2013Assignee: ULVAC, Inc.Inventors: Takafumi Kawaguchi, Kenji Ago, Toshio Koike

Publication number: 20100109220Abstract: Object To provide a substrate assembly apparatus capable of simplifying a structure of the apparatus and performing appropriate detachment of a substrate constantly. Solving Means A substrate assembly apparatus according to the present invention includes a support base and a holding mechanism. The support base is for supporting a lower substrate. The holding mechanism includes a holding surface and a functional element. The holding surface is for holding an upper surface of an upper substrate. The functional element is provided on the holding surface and has a holding force variable in accordance with a magnitude of a voltage. The holding mechanism causes a lower surface of the upper substrate to face an upper surface of the lower substrate supported by the support base. With this structure, it becomes possible to electrically control the holding force with respect to the substrate and simplify the structure of the holding mechanism.Type: ApplicationFiled: April 15, 2008Publication date: May 6, 2010Applicant: ULVAC, INC.Inventors: Kazuhiro Musha, Hirofumi Minami, Takafumi Kawaguchi
