The elucidation of the growth mechanism of amorphous carbon is conducted with a combination of radical measurement and machine learning to improve its etch resistance. In this research, contribution analysis of the machine learning models made it clear that the ion irradiation generated with substrate bias contributes to determining etch resistance when the Hydrogen flow ratio is small. In addition, the effect of synergies between reactive species which determines the film property will be quantitatively discussed based on the ion and radical measurement with a quadrupole mass spectrometer.
