  • What is CVD for SiC

  • Dry Etching vs Wet Etching

    In semiconductor fabrication, etching is one of the major steps, along with photolithography and thin-film deposition. It involves removing unwanted materials from the surface of a wafer using chemical or physical methods. This step is carried out after coating, photolithography, and developing. It is used to remove the exposed thin film material, leaving only the desired portion of the wafer, and then removing the excess photoresist. These steps are repeated numerous times to create complex integrated circuits.

  • 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).

  • Advantages of Silicon Carbide Ceramics in the Optical Fiber Industry

    Silicon carbide ceramics offer numerous advantages in the optical fiber industry, including high-temperature stability, low thermal expansion coefficient, low loss and damage threshold, mechanical strength, corrosion resistance, good thermal conductivity, and low dielectric constant. These properties make SiC ceramics an ideal material for fiber optic sensors, lasers, and high-power optical fiber applications. As demand in the optical fiber field increases, the application prospects for silicon carbide ceramics will become increasingly prominent.

  • 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).

  • Purification Technology of Graphite in SiC semiconductor

    Graphite is vital in producing Silicon Carbide (SiC) semiconductors, known for their exceptional thermal and electrical properties. This makes SiC ideal for high-power, high-temperature, and high-frequency applications. In SiC semiconductor manufacturing, graphite is commonly used for crucibles, heaters, and other high-temperature processing components due to its excellent thermal conductivity, chemical stability, and resistance to thermal shock.
