  • Publication number: 20040044981
    Abstract: CAD (Computer Aided Design) data which is reticle design data is input to first and second data conversion devices which respectively convert the CAD data to electron beam (EB) write data and inspection data. The EB write data and inspection data output are input to a data verification device to verify whether or not there is a data conversion error. If no data conversion error is detected by the data verification device, an EB writing device writes a pattern on an unwritten reticle with an electron beam based on the EB write data and develops the reticle, after which the fabricated developed reticle is inspected by a reticle inspection device. As a defect, such as a data conversion error contained in EB write data is detected before fabrication of a reticle, the reticle inspection process is simplified, the effective availability factors of the EB writing device and reticle inspection device and the time needed to fabricate a reticle is made shorter, thereby reducing the fabrication cost.

  • Patent number: 6346465
    Abstract: A fabrication method of a semiconductor device that realizes a simplified contact formation process is provided. After a single-crystal silicon substrate having a main surface is provided, a dielectric film having a contact hole uncovering the main surface of the substrate is formed on the main surface of the substrate. Next, a silicon nitride film is formed on the main surface of the substrate in the contact hole of the dielectric film. Then, a metal film is formed on the dielectric film to be contacted with the silicon nitride film in the contact hole of the dielectric film. The metal film has a property that an atom of the metal film serves as diffusion species in a solid-phase silicidation reaction. The metal film, the silicon nitride film, the dielectric film, and the substrate are heat-treated to thereby form a metal silicide film due to a solid-phase silicidation reaction between the metal film and the substrate.
