Abstract

In situ optical emission spectroscopy studies of Ti/TiN reactive sputtering were carried out in a Varian M2000 cluster tool. Deposition rates of Ti/TiN films at 4.3 mTorr are directly proportional to ratio of Ti(365)/Ar(435) emission lines. Measurement of the ratio of the N(655)/Ar(435) emission lines indicates an incubative dependence on.nitrogen flow due to nitridation of the target. TiN reactive sputtering is accurately described by a mathematical model based on the nitrogen flux balance on target and wall/shield at steady state.
