  • Patent number: 7251049
    Abstract: When image synthesis using form data, for which a pass code has been set, or merge data, for which a password has been set, is completed, the synthesized data is encoded and held. Thereafter, a client terminal is notified by e-mail that image synthesis has been completed. Thereafter, when a request for output is inputted, collation of passwords is carried out. If the passwords match, decoding and printing-out of encoded synthesized data, or transmission of the encoded synthesized data is carried out.

  • Patent number: 7198886
    Abstract: A method of forming a pattern, which comprises forming a masking material layer on a surface of a working film by coating the surface with a solution of a mixture comprising an inorganic compound having a bond between an inorganic element and oxygen atom, and a volatile unit, volatilizing the volatile unit to thereby make the masking material layer porous, forming a resist layer on a surface of the masking material layer, patterning the resist film to form a resist pattern, dry-etching the masking material layer to thereby transfer the resist pattern to the masking material layer, thereby forming a masking material pattern, and dry etching the working film to thereby transfer the masking material pattern to the working film to thereby form a working film pattern.

  • Patent number: 6846750
    Abstract: According to the present invention, there is provided a method of manufacturing a semiconductor device, where a soluble thin film which is soluble in a dissolving liquid is used. According to the method of the present invention, when a soluble thin film is formed between a film to be processed which should be patterned and a mask pattern, it becomes possible to remove the mask pattern by lifting-off. On the other hand, when the thin film is used for a dummy layer for forming an air wiring structure, the dummy layer can be removed without performing ashing using oxygen plasma.

  • Publication number: 20040144491
    Abstract: A plasma processing apparatus includes a chamber in which a plate to be processed is contained, an introductory port via which a hydrogen-atom-containing gas is guided into the chamber, a lower electrode on which the plate is laid in the chamber, an upper electrode disposed opposite to the lower electrode and causing electric discharge in the chamber to produce a plasma, a power supply which supplies voltage between the lower and upper electrodes, and a metal oxide structural body disposed in a part in the chamber, the metal oxide structural body being reduced when the hydrogen-atom-containing gas is introduced.
