WebJun 4, 1998 · The effects of O 2 and N 2 addition on the etch rate and surface chemistry were established. Admixing O 2 to CF 4 increases the gas phase fluorine density and increases the etch rate by roughly sevenfold to a maximum at an O 2 /CF 4 ratio of 0.15. The addition of small amounts of N 2 (N 2 /CF 4 =0.05) can again double this etch rate … WebMar 1, 2015 · The effect of the O 2 /Ar mixing ratio in CF 4 /O 2 /Ar and C 4 F 8 /O 2 /Ar inductively coupled plasmas with a 50% fluorocarbon gas content on plasma parameters …
