WebJul 8, 2016 · Abstract Stress controllable silicon nitride (SiNx) films deposited by plasma enhanced chemical vapor deposition (PECVD) are reported. Low stress SiNx films were deposited in both high frequency (HF) mode and dual frequency (HF/LF) mode. Webtested α-SiC layers was performed using a STS Multiplex Pro-CVD PECVD system descri‐ bed in detail elsewhere [35, 36]. This system enables two RF deposition modes: a low fre‐ quency (LF) mode at 380 kHz with a tuning power between 0 to 1 kW, and/or a high frequency (HF) mode at 13.56 MHz with a selected power in the range between 0 to 600 W.

WebMar 30, 2024 · Plasma enhanced chemical vapor deposition (PECVD) is a technology that utilizes a plasma to provide some of the energy for the deposition reaction to take place. This provides an advantage of lower temperature processing compared with purely thermal processing methods like low pressure chemical vapor deposition (LPCVD). http://davidlu.net/EtchTable2.pdf
WebOct 31, 2024 · The PECVD process health condition was established as high lifetime at predeposition time of 150 min with the mean health value of 0.58 and the control limits of 0.28. The health value generated can be interpreted and reflected the PECVD process which will provide valuable information for passivation quality of higher lifetime.
