    Study of processes in a pulsed magnetron Ar/O2 plasma by mass spectrometry

  • Original language description

    We studied plasma processes during sputtering of aluminum target in a reactive oxygen/argon atmosphere in two radial positions. The partial pressure of oxygen was systematically changed keeping the total pressure constant (0.5 Pa). A whole target-poisoning cycle was analyzed with a special attention to unstable transition from dielectric to metallic mode. Our attention was focused to appearance of positive O+, O2+, Al +and AlO+ ions. In the radial direction in front of race-track we observed energetic negative ions of O-, O2- and weak ALO- while in the central position the negative ions disappeared. The transition from dielectric to metallic mode is followed by atomic oxygen ions decrease, while the molecular oxygen ions completely disappear from the spectra in the transition mode. The observed plasma behavior was assigned to a mechanism of the film formation.

    Studium procesů v pulsním magnetronovém Ar/O2 plazmatu pomocí hmotnostní spektrometrie

  • Czech description

    Studium procesů v plazmatu během magnetronového odprašování hliníkového terče v reaktivní kyslík/argonové atmosféře ve dvou různých radiálních polohách. Byl analyzován celý cyklus "otravy" terče, kdy pozornost byla věnována nestabilní oblasti přechodu zdielektrického do kovového módu. Byl sledován výskyt a chování O+, O2+, Al+ a AlO+ iontů. Mimo radiální osu byly detekovány záporné ionty O-, O2- a slabě ALO-.
