  • What is a semiconductor?

    Semiconductors are materials that guide electrical properties between conductors and insulators, with equal probability of loss and gain of electrons in the outermost layer of the atomic nucleus, and are easily made into PN junctions. Such as "silicon (Si)", "germanium (Ge)" and other materials.

  • 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.

  • Differences between SiC crystals with different structures

    Silicon carbide (SiC) is a material that possesses exceptional thermal, physical and chemical stability, exhibiting properties that go beyond those of conventional materials. Its thermal conductivity is an astonishing 84W/(m·K), which is not only higher than copper but also three times that of silicon. This demonstrates its enormous potential for use in thermal management applications.

  • The significance of porous graphite materials to SiC crystal growth

    Semicorex's SiC crystal growth furnace component, the porous graphite barrel, will bring three major benefits and can effectively strengthen the competitiveness of domestic SiC substrates:

  • Main steps in SiC substrate processing

    The processing of 4H-SiC substrate mainly includes the following steps:

  • Substrate and Epitaxy

    In the process of wafer preparation, there are two core links: one is the preparation of the substrate, and the other is the implementation of the epitaxial process. The substrate, a wafer carefully made of semiconductor single crystal material, can be directly put into the wafer manufacturing process as a basis to produce semiconductor devices, or further enhance the performance through the epitaxial process.
