  • Publication number: 20010031563
    Abstract: Disclosed is a method of fabricating a semiconductor device, in which an interlayer insulating film having a low dielectric constant is formed by coating a wiring, and either a via hole or a contact hole is formed in the interlayer insulating film. The method of fabricating a semiconductor device having the interlayer insulating film 25 formed on the film-formed substrate 21 with the exposed wiring 23, comprises the step of converting a silicon compound containing only the Si, O, C and H into a plasma gas as a film-forming gas to react the plasma gas, thus forming the block insulating film 24 containing silicon (Si), oxygen (O), carbon (C) and hydrogen (H) between the wiring 23 and the interlayer insulating film 25.

  • Patent number: 5995096
    Abstract: In a conferencing system comprising telephones and workstations to assist a cooperative work, a conference display control method for a visual user interface is provided. A conference window is displayed on a workstation display during execution of a teleconference. The conference window includes a meeting table area as a shared space and a local area which cannot be seen by the other participants. Document objects corresponding to a document application program which is used in the conference are arranged on those areas. The distribution of the documents, reference of information, and execution of the application program can be executed by direct manipulation of objects using a mouse. In the conference window, the document object can be operated at both the cooperative work place and the local work place. The operations during the conference can be simplified.

  • Patent number: 5748894
    Abstract: A cooperative information processing system in which a cooperative execution application program can utilize an auxiliary application program that is being executed locally. The communication control program has the request conversion unit, the input conversion unit and the server-dependent information table. The communication control program utilizes the server-dependent information table to interpret the format of an inter-application message between the sites and carries out a proper conversion. Thus, communication between the cooperative execution application program and the auxiliary application program locally executed at a specific site, such as for example, the Japanese inputting front end program, is made possible.
