Patent number: 11898246Abstract: A vapor deposition device is provided that can ameliorate or improve the LPD quality. A vapor deposition device includes a first holder that supports a carrier at a topmost-level and a second holder that supports the carrier under the first holder in a load-lock chamber, and a second robot mounts a before-treatment wafer extracted from a wafer storage container on the carrier standing by at the first holder in the load-lock chamber.Type: GrantFiled: November 5, 2019Date of Patent: February 13, 2024Assignee: SUMCO CORPORATIONInventors: Naoyuki Wada, Yu Minamide

Publication number: 20230025927Abstract: A vapor deposition device is provided that can correct a positional offset of a carrier in a rotation direction relative to a wafer when the vapor deposition device is viewed in a plan view. The vapor deposition device includes a load-lock chamber provided with a holder for supporting the carrier, and the carrier and the holder are provided with a correction mechanism that corrects a position of the carrier in a rotation direction when the vapor deposition device is viewed in a plan view.Type: ApplicationFiled: October 15, 2020Publication date: January 26, 2023Applicant: SUMCO CORPORATIONInventor: Yu MINAMIDE

Publication number: 20230009579Abstract: A vapor deposition device is provided that can suppress an influence on an epitaxial layer which is caused by a position of a lift pin without adjusting an upper and lower heating ratio of a wafer. A reaction chamber is provided with a susceptor on which a carrier is placed, and a carrier lift pin which moves the carrier vertically relative to the susceptor; and the carrier lift pin is installed outside of an outer edge of the wafer when a state where the carrier supporting the wafer is mounted on the susceptor is viewed in a plan view.Type: ApplicationFiled: November 16, 2020Publication date: January 12, 2023Applicant: SUMCO CORPORATIONInventors: Yu MINAMIDE, Naoyuki WADA

Publication number: 20220199398Abstract: Using the first robot, the carrier standing by in the load lock chamber is deposited into the reaction chamber without mounting the wafer before processing, and cleaning gas is supplied while the reaction chamber is maintained at a predetermined cleaning temperature, and the carrier that has been cleaned in the reaction chamber is transferred to the load lock chamber using the first robot. The carrier and susceptor are cleaned at a predetermined frequency. After that, the carrier is carried out from the reaction chamber, and the reaction gas is supplied to the reaction chamber to form a polysilicon film on the surface of the susceptor.Type: ApplicationFiled: February 7, 2020Publication date: June 23, 2022Applicant: SUMCO CORPORATIONInventors: Naoyuki WADA, Yu MINAMIDE
