  • 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.

  • What is isostatic graphite?

    Isostatic graphite is a type of graphite with an ultra-fine grain. It is used for applications where the mechanical properties of other fine-grained graphites are inadequate.

  • What is quartz?

    Quartz (SiO₂) material is very similar to glass at first glance, but the special thing is that the general glass is made up of many components (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.), while the quartz contains only SiO₂ components, and the microstructure of its silicon dioxide tetrahedral structural units composed of a simple network.

  • Thermal field insulation material

    The process of monocrystalline silicon growth predominantly occurs within a thermal field, where the quality of the thermal environment significantly impacts crystal quality and growth efficiency. The design of the thermal field plays a pivotal role in shaping temperature gradients and gas flow dynamics within the furnace chamber. Furthermore, the materials used in constructing the thermal field directly influence its lifespan and performance.

  • What is a TaC coating on graphite?

    In the rapidly evolving field of semiconductor manufacturing, even the smallest improvements can make a big difference when it comes to achieving optimal performance, durability, and efficiency. One advancement that is generating a lot of buzz in the industry is the use of TaC (Tantalum Carbide) coating on graphite surfaces. But what exactly is TaC coating, and why are semiconductor manufacturers taking notice of it?

  • Advantages of SiC in EV industry

    As a wide-bandgap (WBG) semiconductor material, SiC's wider energy difference gives it higher thermal and electronic properties compared to traditional Si. This feature enables power devices to operate at higher temperatures, frequencies and voltages.
