  • Patent number: 7765466
    Abstract: An information processing method for providing a communication terminal with a service. When editing in a lump of a plurality of held data to which the services are to be applied is received an instruction from the communication terminal, data capable of undergoing the accepted editing is automatically selected from the held data and the selected data is edited. With regard to data automatically judged to be incapable of undergoing the accepted editing, information that reports exclusion of this data from editing is transmitted to the communication terminal and is displayed thereby. That is, when plural items of held data are edited simultaneously, data not suited to this editing is excluded automatically, thereby enhancing user convenience in terms of operation. In addition, the fact that data not suited to editing has not been edited is clearly indicated to the user to prevent miss-recognition by the user.

    Abstract: Provided is an amorphous carbon film having a high elastic modulus and a low thermal contraction rate with a suppressed low dielectric constant, a semiconductor device including the amorphous carbon film and a technology for forming the amorphous carbon film. Since the amorphous carbon film is formed by controlling an additive amount of Si (silicon) during film formation, it is possible to form the amorphous carbon film having a high elastic modulus and a low thermal contraction rate with a suppressed dielectric constant as low as 3.3 or less. Accordingly, when the amorphous carbon film is used as a film in the semiconductor device, troubles such as a film peeling can be suppressed.

  • Publication number: 20070160757
    Abstract: In a processing apparatus which performs a film deposition by alternately supplying a plurality of source gases, the source gases are prevented from reacting within an exhaust pipe so as to prevent the exhaust pipe from clogging due to a reaction by-product. A gas supply to a processing container is switched between a TiCl4 supply system and a NH3 supply system. Additionally, a gas exhaust from the processing container is switched between a TiCl4 exhaust system and a NH3 exhaust system. The gas exhaust is switched to the TiCl4 exhaust system when the gas supply is switched to the TiCl4 supply system, and the gas exhaust is switched to the NH3 exhaust system when the gas supply is switched to the NH3 supply system. The switching is performed by a stop valve provided to each of the supply system and the exhaust system.
