China SiC Susceptor for MOCVD Manufacturers, Suppliers, Factory

In their newly released annual report, TSMC Chairman Deyin Liu and CEO Chieh-Jia Wei revealed the progress related to the 2nm process.

Heat treatment is one of the essential and important processes in the semiconductor process. Thermal process is the process of applying thermal energy to a wafer by placing it in an environment filled with a specific gas, including oxidation/diffusion/annealing, etc.

In modern electronics, optoelectronics, microelectronics, and information technology fields, semiconductor substrates and epitaxial technologies are indispensable. They provide a solid foundation for manufacturing high-performance, high-reliability semiconductor devices. As technology continues to advance, semiconductor substrates and epitaxial technologies will also progress, bringing new breakthroughs and developments to the future of the semiconductor industry.

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.

Within the silicon carbide (SiC) industry chain, substrate suppliers hold significant leverage, primarily due to value distribution. SiC substrates account for 47% of the total value, followed by epitaxial layers at 23%, while device design and manufacturing constitute the remaining 30%. This inverted value chain stems from the high technological barriers inherent to substrate and epitaxial layer production. Three major challenges plague SiC substrate growth: stringent growth conditions, slow growth rates, and demanding crystallographic requirements. These complexities contribute to increased processing difficulty, ultimately resulting in low product yields and high costs. Furthermore, the epitaxial layer’s thickness and doping concentration are critical parameters directly impacting the final device performance.
