Abstract: In a vacuum processing chamber, an etching is performed on an object to be processed having at least a mask layer formed in a predetermined pattern and a Ti layer, as a layer to be etched, formed under the mask layer. During the etching, a first plasma processing is carried out to etch the Ti layer by using a plasma of an etching gas containing a fluorine compound at an inner pressure of the chamber of 4 Pa or less. Subsequently, a second plasma processing for dry cleaning is performed by using a plasma of a cleaning gas after the first plasma processing is completed. At this time, a deposit containing a Ti compound produced during the plasma processing is removed.

Abstract: A plurality of letter output devices (workstations, printers) are connected to a letter data control device by a transmission path. The control device stores letter data for transmission to the letter output devices, and is able to convert that letter data to a desired layout (e.g. from a vector font to a dot font) and then transmits the converted letter data to one or more of the letter output devices. The control device is able to select part of its stored letter data for transmission so that only commonly used letter data need be transmitted during start up of the system. Since a large amount of letter data may be stored in the control device, and only part may be transmitted to the letter output devices, those output devices can have a relatively small memory.
