ABSTRACTOptical Emission Spectroscopy (OES) with argon actinometry has been used to study the influence of machine parameters on the composition of a BCl3 RF plasma discharge in the absence and presence of aluminium. Two steady state models are proposed to account for the appearance of the various species seen, and to explain their relative abundances in response to changes in power and pressure. The validity of the actinometric technique for measuring relative changes in ground state concentrations is discussed also.
