摘要: Abstract This work highlights optical emission spectroscopy (OES) results used for a better understanding of processes occuring in radiofrequency and microwave plasma enhanced chemical vapor deposition the Si-C-H-Ar gas system. Optical lines such as Si + H α (λ = 634.71; 656.29 nm), C 2 516.52 CH SiH 431.42; 412.80 nm) can be considered tracers species plasmas. Process parameters (growth rate, composition, residual stresses films temperature) have their signatures (respectively: , rotational G 1 Σ g → B u structure ).
