Quadrupole mass-spectroscopy has reported significant neutral and ionic species in the unique C 5 HF 7 /O 2 /Ar plasma, including C x F y (X>2), C x HF y, and C x F y (Y/X<2). Using C 5 HF 7 /O 2 /Ar ...
In dry etching, the trajectory of accelerated ions is non-uniform and non-vertical, due to collisions with gas molecules and other random thermal effects (figure 1). This has an impact on etch results ...
