VET Energy PECVD process graphite carrier is a high-quality consumable tailored for PECVD (plasma enhanced chemical vapor deposition) process. This graphite carrier is made of high-purity, high-density graphite material, with excellent high temperature resistance, corrosion resistance, dimensional stability and other characteristics, can provide a stable carrier platform for PECVD process, to ensure the uniformity and flatness of thin film deposition.
Graphite carriers for PECVD process have the following characteristics:
▪ High purity: extremely low impurity content, avoiding contamination of the film and ensuring film quality.
▪ High density: high density, high mechanical strength, able to withstand high temperature and high pressure PECVD environment.
▪ Good dimensional stability: small dimensional change at high temperature, ensuring process stability.
▪ Excellent thermal conductivity: effectively transfer heat to prevent wafer overheating.
▪ Strong corrosion resistance: able to resist erosion by various corrosive gases and plasma.
▪ Customized service: graphite carriers of different sizes and shapes can be customized according to customer needs.
