  • Patent number: 9805960
    Abstract: When an edge of a wafer passes above a right sensor and a left sensor disposed in a conveyance route of the wafer to a substrate processing chamber, four edge intersecting points are acquired in a first wafer coordinate system, and a reference edge intersecting point set composed of two adjacent edge intersecting points is created from the four edge intersecting points. Between the two remaining edge intersecting points which do not constitute the reference edge intersecting point set, an edge intersecting point present within an area surrounded by two circles defined based on the two edge intersecting points constituting the reference edge intersecting point set is selected as an effective edge intersecting point, and a central position of a circle passing through the reference edge intersecting points and the effective edge intersecting point is acquired as a central position of the wafer.

  • Publication number: 20170004992
    Abstract: A transfer device can have a high durability and no limit in an operation of an arm member. An electrostatic pick 44 of a first transfer device 17 is advanced into a process module 12, and a wafer W is electrostatically attracted to and held on the electrostatic pick 44. While the wafer W is being transferred into a load lock module 14 by driving the first transfer device 17, the electrostatic pick 44 is turned into an electrically floating state, so that a state in which the wafer W is electrostatically attracted to and held on the electrostatic pick 44 is maintained. After the transferring of the wafer W to the load lock module 14 is completed, charges of the electrostatic pick 44 are neutralized, so that the wafer W is not electrostatically attracted to and held on the electrostatic pick 44.

  • Patent number: 9082798
    Abstract: Even in case that a wafer is so greatly deviated that a peripheral portion of the wafer cannot be detected, position determination of the wafer can be performed without inflicting a damage on the wafer. The wafer peripheral portion, which is a target, is detected based on output images from a plurality of imaging units disposed along a peripheral portion shape of the wafer (step S210), and a wafer position deviation correcting step (step S220) or a rough correcting step (step 230) is performed according to the number of the imaging units capable of detecting the wafer peripheral portion. In case that the wafer peripheral portion cannot be detected by all the imaging units, a wafer position adjusting step (step 240) for moving the wafer is performed in a position adjusting direction acquired by a combination of the output images by each imaging unit.

  • Patent number: 8216382
    Abstract: A foreign matter removal method that removes foreign matter attached to a surface of a substrate having been subjected to predetermined processing. An edge of a rotating substrate mounted on a mounting stage is irradiated with misalignment measurement laser light. The misalignment measurement laser light other than the laser light blocked by the edge of the substrate is received, and power thereof is detected. The amount of misalignment of the substrate is calculated based on the detected power of the misalignment measurement laser light and a detected rotation angle of the rotating substrate. The misalignment of the substrate is corrected for based on the calculated amount of misalignment. After that, foreign matter removal laser light is irradiated, and a process gas that is to react with the foreign matter is jetted to the edge of the substrate. Consequently, the foreign matter attached to the substrate is decomposed and removed.
