Silicon carbide (SiC) is highly favored in the semiconductor industry for its excellent physical and chemical properties. However, the high hardness and brittleness of SiC pose considerable challenges to its processing.

When producing large-sized GaN single crystal substrates, HVPE is currently the best choice for commercialization. However, the back carrier concentration of the grown GaN cannot be precisely controlled.

High-purity quartz possesses remarkable physical and chemical properties. Its inherent crystal structure, shape, and lattice variations contribute to exceptional characteristics such as high-temperature resistance, corrosion resistance, abrasion resistance, low thermal expansion coefficient, high insulation, piezoelectric effects, resonant effects, and unique optical properties. These attributes make it an irreplaceable foundational material for the development of strategic and pillar industries.

The silicon carbide industry involves a chain of processes that include substrate creation, epitaxial growth, device design, device manufacturing, packaging, and testing. In general, silicon carbide is created as ingots, which are then sliced, ground, and polished to produce a silicon carbide substrate.

Silicon carbide (SiC) ceramic materials possess a range of excellent properties, including high-temperature strength, strong oxidation resistance, superior wear resistance, thermal stability, low thermal expansion coefficient, high thermal conductivity, high hardness, thermal shock resistance, and chemical corrosion resistance. These characteristics make SiC ceramics increasingly applicable in various fields such as automotive, mechanical and chemical industries, environmental protection, space technology, information electronics, and energy. SiC ceramics have become an irreplaceable structural ceramic material in many industrial sectors due to their outstanding performance.

In the realm of semiconductor device fabrication, the precise control of crystal growth is paramount for achieving high-quality and reliable devices. One technique that has played a pivotal role in this domain is Liquid-Phase Epitaxy (LPE).
