Low-stress silicon nitride layers for MEMS applications ...

The paper presents two deposition methods for generation of SiN _x layers with "zero" residual stress in PECVD reactors: mixed frequency and high power in high frequency mode (13.56 MHz). Traditionally, mix frequency mode is commonly used to produce low stress SiN _x layers, which alternatively applies the HF and LF mode. However, due to the low deposition rate of LF mode ...

Silicon Nitride Films - Silicon Valley Microelectronics

Silicon Nitride Films. Silicon nitride (Si3N4,SiN) offers excellent mechanical and thermal stability. It is commonly used for hard masks, as a dielectric material, or as a passivation layer. Silicon nitride is very hard by nature and has good thermal shock resistance and oxidation resistance. SVM offers two types of nitride films: LPCVD and PECVD.
