Silicon carbide (SiC) plays an important role in manufacturing power electronics and high-frequency devices due to its excellent electrical and thermal properties. The quality and doping level of SiC crystals directly affect the performance of the device, so precise control of doping is one of the key technologies in the SiC growth process.

Silicon carbide has a large number of applications in emerging industries and traditional industries. At present, the global semiconductor market has exceeded 100 billion yuan. It is expected that by 2025, the global sales of semiconductor manufacturing materials will reach 39.5 billion US dollars, of which the silicon carbide semiconductor market is expected to reach a market size of 2.5 billion US dollars in 2025. At the same time, silicon carbide is still the material with the best application performance in traditional ceramics, refractory, high temperature, grinding and other fields.

Crystal growth is the core link in the production of Silicon Carbide substrates, and the core equipment is the crystal growth furnace. Similar to traditional crystalline silicon-grade crystal growth furnaces, the furnace structure is not very complex and mainly consists of a furnace body, a heating system, a coil transmission mechanism, a vacuum acquisition and measurement system, a gas path system, a cooling system, a control system, etc., among which Thermal field and process conditions determine the quality, size, conductive properties and other key indicators of Silicon Carbide crystals.

This paper provides a comprehensive overview of the various manufacturing techniques employed to produce dense SiC ceramics, highlighting their unique characteristics and applications.

As technology nodes continue to shrink, the formation of ultra-shallow junctions presents significant challenges. Thermal annealing processes including Rapid thermal annealing (RTA) and flash lamp annealing (FLA) are vital techniques that maintain high impurity activation rates while minimizing diffusion, ensuring optimal device performance.

SiC substrates are the most crucial component in the silicon carbide industry, accounting for nearly 50% of its value. Without SiC substrates, it is impossible to manufacture SiC devices, making them the essential material foundation.
