Overview

The TOYO TANSO GROUP contributes to society by pursuing the possiblities inherent in carbon. We have just estblished TOYO TANSO SINGAPORE PTE LTD in the hope of building a cooperative relationship with local valued customers. "Semi-Conductor and Solar Cells Applications" Graphite is an indispensable material in a variety of applications, including crucibles and heaters for single crystal silicon pulling furnaces, SiC graphite coatings for epitaxial growth systems (used in growing films on the surface of semi-conductor wafers), and in solar cell and liquid crystal display manufacture.


  Products

  • PERMA KOTE™ Susceptors (SiC coated Graphite)
    Due to their excellent chemical resistance, dust resistance, and dimensional precision, Toyo Tanso's PERMA KOTE™ products are widely used in epitaxial wafer manufacturing processes.
    ...

  • In the epitaxial process, silicon wafers are heated in an epitaxial furnace to around 1200°C, and vaporized silicon tetrachloride (SiCl4) and silane trichloride (SiHCl3) are added to the furnace to induce epitaxial growth on the surface of the wafers.

    PERMA KOTE™ susceptors (SiC coated)--which have excellent thermal durability, chemical resistance, and dust resistance--are therefore extensively employed.

    Moreover, because susceptors come into contact with the wafers, their dimensional precision and surface roughness affect wafer temperature distribution. SiC layers with high dimensional precision and smoothness are therefore required.

    Thanks to proprietary technology for graphite substrate processing and SiC layer control combined with technical support that leverages our superb analytic capabilities, Toyo Tanso can offer the ideal product to suit your requirements.

  • Crucible & Heater
    Toyo Tanso provides a range of graphite products for use as parts in monocrystalline silicon processes (CZ furnaces). We are also able to supply large-diameter products and long-life surface-treated products....

  • When pulling monocrystalline silicon, melting temperature is extremely high at approximately 1500°C, but isotropic graphite's excellent thermal durability helps extend product life.

    High-purity products are used in environments where it is necessary to avoid contaminants; coating products (PERMA KOTE® and PYROGRAPH®) are used in environments where it is necessary to avoid particles and reactions with desorbed gas and SiO gas; and lightweight, easy-to-handle C/C composites are used in large furnaces.

    Crucible
    To protect the quartz crucible used in the manufacture of single crystal silicon, many manufacturers are using our high purified isotropic graphite as it provides high strength and minimal wear.

    Heater
    Graphite can be purified down to the ppm order as well as easily machined to complicated forms. It is an absolutely necessary material for the heating elements used in semiconductor manufacture.

  • MOCVD Susceptor
    Thanks to their excellent chemical resistance, dust resistance, and dimensional precision, PERMA KOTE™ products are widely used in LED manufacturing processes....

  • The MOCVD process involves the use of ammonia (NH3) gas, which makes it impossible to avoid early corrosion when using non-coated graphite, and also requires a high-purity, dust-proof environment. PERMA KOTE™ susceptors (SiC coated) are therefore widely employed for their excellent thermal durability and chemical- and dust-resistant properties.

    Moreover, because susceptors come into contact with the wafers, their dimensional precision and surface roughness affect wafer temperature distribution. SiC layers with high dimensional precision and smoothness are therefore required.

    Thanks to proprietary technology for graphite substrate processing and SiC layer control combined with technical support that leverages our superb analytic capabilities, Toyo Tanso can offer the ideal product to suit your requirements.

  • Graphite Sheets (PERMA-FOIL®)
    PERMA-FOIL® is a flexible graphite sheet which ensure a snug fit with contacting parts, therefore it is widely used as a seal, to note automotive gaskets and packing....

  • PERMA-FOIL® is a generic term for the flexible graphite sheet that Toyo Tanso developed through our original manufacturing technology. It is a sheet graphite product that is formed using select acid treated natural graphite, which is then compressed after undergoing high temperature expansion. Only natural graphite is used as a raw material, which yields highly flexible carbon with excellent heat resistance and chemical resistance. Other features include a high compressibility recovery rate, excellent airtightness, and a high thermal conductivity.
  • Carbon Brush
    Because of the sliding contact they make, motor brushes play an important part in flowing electric current between stationary and rotary parts....

  • The carbon brush plays the important role of sending electrical current between motionless and rotating parts by sliding contact. Since the performance of the brush has significant impact of the performance of rotating machine, the choice of brush is a critical factor.

    At the Toyo Tanso Group, we develop and produce carbon brushes for a variety of customer needs and purposes, applying the superior technology and quality assurance know-low that we have developed over our many years of research in the fields. Our products exude minimum impact on the environment, and can be used for many different applications.
