  • TaC Coating

    According to the research results, TaC coating can act as a protection and isolation layer to extend graphite component life, improve radial temperature uniformity, maintain SiC sublimation stoichiometry, suppress impurity migration, and reduce energy consumption. Ultimately a TaC-coated graphite crucible set is expected to improve SiC PVT process control and product quality.

  • Applications of TaC Coated Graphite Components

    In the process of growing SiC and AlN single crystals by the physical vapor transport method (PVT), components such as the crucible, seed crystal holder and guide ring play a vital role. During the preparation process of SiC, the seed crystal is located in a relatively low temperature region, while the raw material is in a high temperature region exceeding 2400°C. The raw materials decompose at high temperatures to form SiXCy (including Si, SiC₂, Si₂C and other components).

  • Oxidation Process

    The most basic stage of all processes is the oxidation process. The oxidation process is to place the silicon wafer in an atmosphere of oxidants such as oxygen or water vapor for high-temperature heat treatment (800~1200℃), and a chemical reaction occurs on the surface of the silicon wafer to form an oxide film (SiO2 film).

  • Defect-Free Epitaxial Growth and Misfit Dislocations

    Defect-free epitaxial growth occurs when one crystal lattice has nearly identical lattice constants to another. Growth happens when lattice sites of the two lattices at the interface region are approximately matched, which is possible with a small lattice mismatch (less than 0.1%). This approximate matching is achieved even with elastic strain at the interface, where each atom is slightly displaced from its original position in the boundary layer. While a small amount of strain is tolerable for thin layers and even desirable for quantum well lasers, the strain energy stored in the crystal is generally lowered by the formation of misfit dislocations, which involve a missing row of atoms in one lattice.

  • SiC Coated Susceptors in MOCVD Processes

    CVD SiC coated susceptors function as specialized wafer holders in Metal-Organic Chemical Vapor Deposition (MOCVD) processes, playing a crucial role in semiconductor fabrication. These components are vital for maintaining the structural integrity of wafers during epitaxy under extreme conditions, such as high temperatures and corrosive environments. **

  • What are The Glass Wafers?

    With the development of semiconductor and optical technologies, glass wafers as the new type of glass product, are gradually becoming a complement to silicon wafers, showing great potential in the field of high technology. What are the glass wafers? Glass wafers are the high-performing circular thin slices, commonly made of quartz glass, alkali-free glass, or glass-silicon composites. With excellent physical and chemical properties, they play an irreplaceable roles in cutting-edge manufacturing fields, such as semiconductor manufacturing, optics, MEMS, consumer electronics, biomedicine, and laboratory research.
