Low stress SiNx films were … WebDirect PECVD techniques are separated into two classes according to the plasma excitation frequency: high-frequency (HF-PECVD) at 13.56 MHz and low-frequency (LF-PECVD) at 10-500 kHz. The principal difference between these techniques is that in the case of LF-PECVD, low-mass ions such as hydrogen can follow the applied radio frequency (R-F)
