TaC coating is an advanced high-temperature protective material with superior thermal stability compared to SiC. It provides excellent resistance to corrosion, oxidation, and wear, and can operate reliably in environments exceeding 2000°C. As a result, it is widely applied in ultra-high-temperature aerospace hot-section components and next-generation third-generation semiconductor crystal growth processes.
Semicera provides advanced, specialized tantalum carbide (TaC) coatings for a wide range of semiconductor components and wafer carriers. Leveraging its leading coating technology, Semicera delivers TaC coatings with ultra-high purity, exceptional high-temperature stability, and excellent chemical resistance, significantly improving the quality of SiC/GaN crystal growth and epitaxial (EPI) processes.
By applying TaC-coated graphite components such as susceptors, rings, and reactor parts, the system effectively reduces edge effects, improves thermal field uniformity, and enhances overall crystal quality. Semicera has achieved a breakthrough in CVD TaC coating technology, reaching internationally advanced performance levels.
After years of continuous development, Semicera’s R&D team has successfully mastered and optimized CVD (Chemical Vapor Deposition) TaC coating technology.
During SiC wafer growth processes, defects such as edge dislocations and non-uniform growth can easily occur. The application of TaC coatings significantly reduces these issues. Comparative results clearly show that wafers processed with TaC-coated components exhibit improved surface uniformity and reduced defect density.
Compared with traditional SiC coatings, Semicera’s TaC coatings provide:
Compared with conventional graphite or SiC-coated parts, TaC-coated components demonstrate significantly improved performance in crystal growth stability, defect control, and thermal field uniformity.
Semicera’s TaC coating technology provides a key solution for next-generation SiC and GaN crystal growth equipment. With its ultra-high purity, outstanding thermal stability, and superior chemical resistance, TaC coatings are becoming an essential material for advanced semiconductor manufacturing.
