Patents by Inventor Atsushi Itou

Atsushi Itou has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6463678
    Abstract: This invention relates to a vacuum processing apparatus having vacuum processing chambers the insides of which must be dry cleaned, and to a method of operating such an apparatus. When the vacuum processing chambers are dry-cleaned, dummy substrates are transferred into the vacuum processing chamber by substrates conveyor means from dummy substrate storage means which is disposed in the air atmosphere together with storage means for storing substrates to be processed, and the inside of the vacuum processing chamber is dry-cleaned by generating a plasma. The dummy substrate is returned to the dummy substrate storage means after dry cleaning is completed. Accordingly, any specific mechanism for only the cleaning purpose is not necessary and the construction of the apparatus can be made simple.

  • Patent number: 6460270
    Abstract: A vacuum processing apparatus which includes a means for transferring wafer cassettes from a transferring chamber to a lock chamber. The wafer cassettes are mounted within a cassette table in a vertical direction and a first transferring means carries a wafer to and from the cassette tables. The vacuum processing apparatus further includes lock chambers into which the wafers are carried my the first transferring means. A second transferring means carries the wafers to either of the lock chambers.
