  • Publication number: 20070077737
    Abstract: A microwave is radiated into a processing chamber (1) from a planar antenna member of an antenna (7) through a dielectric plate (6). With this, a C5F8 gas supplied into the processing chamber (1) from a gas supply member (3) is changed (activated) into a plasma so as to form a fluorine-containing carbon film of a certain thickness on a semiconductor wafer (W). Each time a film forming process of forming a film on one wafer is carried out, a cleaning process and a pre-coating process are carried out. In the cleaning process, the inside of the processing chamber is cleaned with a plasma of an oxygen gas and a hydrogen gas. In the pre-coating process, the C5F8 gas is changed into a plasma, and a pre-coat film of fluorine-containing carbon thinner than the fluorine-containing carbon film formed in the film forming process is formed.

  • Publication number: 20050002590
    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.

  • Publication number: 20040250765
    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.

  • Publication number: 20040212114
    Abstract: 1,3,5-trimethyl-1,3,5-trivinylcyclotrisiloxane (V3D3) and isopropyl alcohol (IPA) are supplied to a chamber 12, and they are excited by plasma to generate molecular active species of these compounds. These active species are reacted in the vicinity of the surface of a substrate to form an insulating thin film with a thickness of, for example, 50 nm containing IPA molecules. Moreover, the IPA molecules contained in the thin film are selectively desorbed by plasma process using ammonium gas to form uniform holes in the thickness direction. The film forming process and the hole forming process are repeatedly executed by a plurality of times, thereby making it possible to obtain an insulating film with a predetermined thickness and holes formed uniformly.
