i use gas of Silane and Phosphine using PECVD if i use
SiH4 (5% diluted in H2) with 20 SCCM as silane flow rate and PH3 (0.5% diluted in H2)2SCCm as phosphine flow rate
i want to know the PH3/SiH4=?? how to calculate it in % and can it be converted in Cm^-3?? pleas help and show me the formula that can handle this problem.
