Abstract
The deposition of silicon oxychloride films on chamber walls during Cl2/O2 plasma etching of Si was discussed. The Cl content and deposition rate of the films were quantified using the position of the Si-O peak and Si-O and OSi-Cl infrared absorption intensities. It was proposed that the silicon oxychloride film was deposited through oxidation of SiClx molecules adsorbed on the reactor walls.
