  • Application Scenarios for Epitaxial Layers

    We know that further epitaxial layers need to be built on top of some wafer substrates for device fabrication, typically LED light-emitting devices, which require GaAs epitaxial layers on top of silicon substrates; SiC epitaxial layers are grown on top of conductive SiC substrates for building devices such as SBDs, MOSFETs, etc. for high voltage, high current and other power applications; GaN epitaxial layers are built on top of semi-insulating SiC substrates for building HEMTs and other RF applications.

  • TaC coating with CVD method

    Tantalum carbide coating is an important high-strength, corrosion-resistant and chemically stable high-temperature structural material with a melting point of up to 4273 °C, one of the several compounds with the highest temperature resistance. It has excellent high-temperature mechanical properties, resistance to high-speed airflow scouring, ablation resistance, and good chemical and mechanical compatibility with graphite and carbon/carbon composites. Therefore, in the epitaxial process of GaN LEDs and SiC power devices such as MOCVD, TaC coating has excellent acid and alkali resistance to H2, HCl, NH3, which can completely protect the graphite substrate material and purify the growth environment.

  • Introducing Gallium Oxide(Ga2O3)

    Gallium oxide (Ga2O3) as an "ultra-wide bandgap semiconductor" material has garnered sustained attention. Ultra-wide bandgap semiconductors fall under the category of "fourth-generation semiconductors," and in comparison to third-generation semiconductors such as silicon carbide (SiC) and gallium nitride (GaN), gallium oxide boasts a bandgap width of 4.9eV, surpassing silicon carbide's 3.2eV and gallium nitride's 3.39eV. A wider bandgap implies that electrons require more energy to transition from the valence band to the conduction band, endowing gallium oxide with characteristics like high voltage resistance, high-temperature tolerance, high power capability, and radiation resistance.

  • What are the challenges of silicon carbide substrate production?

    Silicon carbide (SiC) is a material that possesses high bond energy, similar to other hard materials like diamond and cubic boron nitride. However, the high bond energy of SiC makes it difficult to crystallize directly into ingots via traditional melting methods. Therefore, the process of growing silicon carbide crystals involves the use of vapor phase epitaxy technology.

  • SiC Single Crystal Substrate Processing

    Silicon Carbide (SiC) single crystals are primarily produced using the sublimation method. After removing the crystal from the crucible, several intricate processing steps are required to create usable wafers.

  • Homoepitaxy and Heteroepitaxy Explained Simply

    Homoepitaxy and heteroepitaxy play pivotal roles in material science. Homoepitaxy involves the growth of a crystalline layer on a substrate of the same material, ensuring minimal defects due to perfect lattice matching. In contrast, heteroepitaxy grows a crystalline layer on a different material substrate, which can lead to challenges like lattice mismatch. These processes are crucial in advancing semiconductor devices and thin films. For instance, heteroepitaxy significantly impacts microelectronics and quantum optics, contributing to innovations like Light Emitting Diodes.
