  • Publication number: 20150270151
    Abstract: A substrate processing apparatus according to the present invention comprises a transferring device including a grasping section configured to grasp a substrate holder, and a transferring section configured to transfer the substrate holder grasped by the grasping section, and a processing bath for storing a substrate held by the substrate holder so that a surface of the substrate is vertically oriented, and processing the substrate. The grasping section is configured to grasp the substrate holder with a surface of the substrate oriented horizontally. The transferring section is configured to transfer the substrate holder above the processing bath, with the surface of the substrate oriented horizontally.

  • Patent number: 8550875
    Abstract: A method of operating a substrate processing apparatus, upon the occurrence of a nonfatal failure in the apparatus, makes it possible to continue part of the apparatus operations for substrates to clean and recover a substrate or to easily discharge a substrate from the apparatus, without stopping an entire apparatus, thereby reducing the risk of a substrate becoming unprocessable. The method of operating a substrate processing apparatus having a polishing section, a cleaning section and a transferring mechanism, includes: classifying substrates, upon detection of a malfunction in any of the polishing section, the cleaning section and the transferring mechanism, according to the site of the malfunction and to the positions of the substrates in the substrate processing apparatus; and carrying out an operation for each of the substrates after the detection of the malfunction, the operation varying depending on the classification of the substrate.

  • Patent number: 8398811
    Abstract: A polishing apparatus has a polishing section (302) configured to polish a substrate and a measurement section (307) configured to measure a thickness of a film formed on the substrate. The polishing apparatus also has an interface (310) configured to input a desired thickness of a film formed on a substrate to be polished and a storage device (308a) configured to store polishing rate data on at least one past substrate therein. The polishing apparatus includes an arithmetic unit (308b) operable to calculate a polishing rate and an optimal polishing time based on the polishing rate data and the desired thickness by using a weighted average method which weights the polishing rate data on a lately polished substrate.

  • Patent number: 8128458
    Abstract: A polishing apparatus detects the escape of a substrate from a top ring during polishing. The polishing apparatus includes a polishing table having a polishing pad, a top ring, and a substrate escape detection section for detecting escape of the substrate from the top ring. The detection section includes a light irradiation member for irradiating an area of the upper surface of the polishing pad with light, a controller for controlling the light irradiation of the light irradiation member, an image-taking member for taking an image of the area irradiated with the light, and an information processing member for processing information outputted from the image-taking member. The controller controls the light irradiation member in such a manner that it performs light irradiation at least for a period of time during which the substrate is regarded as being in contact with the polishing pad.
