Energy flux measurements during magnetron sputter deposition processes

Résumé

The influence of energetic species on thin film growth mechanism is a long-term issue in the field of low-pressure plasma-based magnetron sputtering technology. Several species may contribute to the energy flux such a plasma ions, electrons and neutrals, film-forming species, photons, etc. Several research groups have designed probes capable of quantifying energy fluxes in these particular working conditions and experimental strategies to get a better insight on the relationship between the plasma working parameters, the energy flux, the film growth mechanism and the coating properties. In this paper we aim at showing how the thermopilebased probe developed at GREMI laboratory can contribute to this field thanks to its time resolved capability (~ms) and sensitivity (~mW/cm 2). We show how such a probe can be used to identify and quantify energetic contributions such as gas conduction, chemical reactions on surfaces such as oxidation, but also radiations emitted from a (hot) sputter target during DC,
