A method and system are presented for monitoring the optical emissions associated with a plasma used in integrated circuit fabrication. The optical emissions may be processed by an optical spectrometer to obtain a spectrum. The spectrum may be analyzed to determine the presence of particular disassociated species which are indicative of the presence of a suitable plasma and which may be desired for a deposition, etching, or cleaning process.
