Patent number: 6746197Abstract: A substrate processing apparatus comprises a processing section for performing processing for a substrate, a substrate carrier transfer section into/out of which a substrate carrier holding a plurality of substrates is carried, and a substrate transfer mechanism for taking an unprocessed substrate out of the substrate carrier carried into the substrate carrier transfer section to deliver it to the processing section and for receiving a processed substrate from the processing section to deliver it into the substrate carrier placed on the substrate carrier transfer section. The substrate carrier transfer section shifts the position of the substrate carrier between a first position at which the substrate carrier is carried to/from the outside and a second position at which the substrate in the substrate carrier is delivered to/from the substrate transfer mechanism.Type: GrantFiled: July 25, 2002Date of Patent: June 8, 2004Assignee: Tokyo Electron LimitedInventors: Yoshio Kimura, Issei Ueda, Mitiaki Matsushita, Kazuhiko Ito

Patent number: 5685039Abstract: A cleaning apparatus includes a spin chuck for holding and rotating a wafer, a brush for rubbing the surface of the wafer, and an arm for supporting the brush. A support is coupled to the arm through a linear guide. The arm and the support moves together in a horizontal direction and can relatively displace in a vertical direction. A compression spring is arranged between the arm and the support and deformed in accordance with a relative displacement of the arm and the support in the vertical direction. When the brush contacts the wafer held by the spin chuck, a biasing force of the brush against the wafer is generated in correspondence with deformation of the compression spring. The biasing force of the brush is set by adjusting the downward moving amount of the support in the vertical direction.Type: GrantFiled: May 10, 1996Date of Patent: November 11, 1997Assignee: Tokyo Electron LimitedInventors: Tomoko Hamada, Mitiaki Matsushita, Kiyohisa Tateyama, Akira Yonemizu
