  • Methods of AlN Crystal Growth

    AlN, as third-generation semiconductor material, is not only an important blue light and ultraviolet light material, but also an important packaging, dielectric isolation and insulation material for electronic devices and integrated circuits, especially suitable for high-temperature and high-power devices. In addition, AlN and GaN have a good thermal match and chemical compatibility, AlN used as GaN epitaxial substrate, can significantly reduce the defect density in GaN devices, improve device performance.

  • 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.

  • A Brief History of Silicon Carbide and Applications of Silicon Carbide Coatings

    The history of silicon carbide (SiC) dates back to 1891, when Edward Goodrich Acheson accidentally discovered it while attempting to synthesize artificial diamonds. Acheson heated a mixture of clay (aluminosilicate) and powdered coke (carbon) in an electric furnace. Instead of the expected diamonds, he obtained a bright green crystal adhering to the carbon. This crystal had a hardness second only to diamond, and was thus named carborundum. In 1904, French-Jewish chemist Henri Moissan discovered rare natural silicon carbide minerals while studying meteorite samples from the Diablo Canyon in Arizona, USA. He named these minerals moissanite, and his discovery earned him the 1906 Nobel Prize in Chemistry.

  • Introduction to the Silicon Carbide Ion Implantation and Annealing Process

    In traditional silicon power device fabrication, high-temperature diffusion and ion implantation stand as the primary methods for dopant control, each with its advantages and disadvantages. Typically, high-temperature diffusion is characterized by its simplicity, cost-effectiveness, isotropic dopant distribution profiles, and lower introduction of lattice damage. Conversely, ion implantation, though complex and costly, enables precise independent control over dopant concentration and depth but introduces a significant number of point defects and extended defects into the substrate.

  • 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.

  • Annealing

    Annealing after ion implantation is a key step in semiconductor device manufacturing, which affects the performance and reliability of the device.
