Abstrakt: Carbon atom densities in an inductively coupled radio frequency (13.56 MHz) CO and CO and H2mixed plasmas were successfully measured for the first time using ultra-violet absorption spectroscopy (UVAS) with a carbon hollow cathode lamp. This method, developed for monitoring carbon atoms in-situ in the plasmas, is very useful for the investigation of etching and chemical vapor deposition (CVD) processes containing carbon atoms and the sputtering system employing a carbon target.
