TaC coated graphite guide ring

Short Description:

In the continuous development of semiconductor processes, the emergence of 8-inch silicon carbide (SiC) wafers has made temperature requirements more stringent. However, traditional base materials cannot cope with the challenges under high temperatures and are prone to sublimation and damage the epitaxial process. To solve this problem, Semicera launched the CvD Tantalum Carbide (TaC) product line. Our Tantalum Carbide (TaC) can withstand extreme temperatures up to 2300 degrees Celsius and provide a longer service life. Welcome to contact Semicera to learn more about our advanced solutions, including customized options for Tantalum Carbide coated cover plates. We are committed to bringing breakthrough advances to your semiconductor process and ensuring efficient and stable production.

TaC coating is a kind of tantalum carbide (TaC) coating prepared by physical vapor deposition technology, it has the following characteristics:

1. High hardness: TaC coating hardness is high, usually can reach 2500-3000HV, is an excellent hard coating.

2. Wear resistance: TaC coating is very wear-resistant, which can effectively reduce the wear and damage of mechanical parts during use.

3. Good high temperature resistance: TaC coating can also maintain its excellent performance under high temperature environment.

4. Good chemical stability: TaC coating has good chemical stability and can resist many chemical reactions, such as acids and bases.
