The liquid phase method is closer to the thermodynamic equilibrium conditions and is able to grow SiC crystals with better quality.

Graphitising is the process of transforming non-graphitic charcoal into graphitic charcoal with graphite three-dimensional regular ordered structure by high-temperature heat treatment, making full use of electrical resistance heat to heat the charcoal material to 2300~3000 ℃, and transforming the charcoal with amorphous chaotic layer structure into ordered graphite crystalline structure.

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.

The third-generation wide bandgap semiconductor materials, such as Gallium Nitride (GaN) and Silicon Carbide (SiC), are renowned for their exceptional optoelectronic conversion and microwave signal transmission capabilities. These materials meet the demanding requirements of high-frequency, high-temperature, high-power, and radiation-resistant electronic devices. Therefore, they have vast application prospects in new-generation mobile communications, new energy vehicles, smart grids, and LED technologies. The comprehensive development of the third-generation semiconductor industry urgently requires breakthroughs in key core technologies, continual advancement in device design and innovation, and a resolution to import dependencies.

The three primary methods used in monocrystalline silicon manufacturing are the Czochralski (CZ) method, the Kyropoulos method, and the Float Zone (FZ) method.

Silicon carbide (SiC) is a wide-bandgap semiconductor material that has garnered significant attention in recent years due to its exceptional performance in high-voltage and high-temperature applications. This study systematically explores the various characteristics of SiC crystals grown using modified process conditions.
