Patent number: 8707893Abstract: A substrate treatment system includes a plurality of treatment apparatuses, a position adjustment apparatus adjusting a center position of the substrate, a substrate transfer apparatus transferring the substrate to the treatment apparatuses and the position adjustment apparatus, and a control unit controlling operations of the apparatuses. The substrate transfer apparatus includes an arm part curved along a peripheral edge portion of the substrate with a radius of curvature larger than a radius of the substrate, and a holding part projecting inward from the arm part and holding a rear surface of the substrate. The position adjustment apparatus includes a mounting table which holds a central portion of the rear surface of the substrate and is rotatable and horizontally movable. The control unit controls the mounting table such that the center position of the substrate held on the mounting table is aligned with a center position of the arm part.Type: GrantFiled: November 18, 2011Date of Patent: April 29, 2014Assignee: Tokyo Electron LimitedInventors: Masatoshi Deguchi, Hideo Funakoshi, Toshichika Takei, Norifumi Sato, Wataru Kiyota, Daisuke Ishimaru, Shinichi Machidori, Ikuo Sunaka, Shigenori Kamei
