Thermal stability of gaz sf6 associated with metallic conductors

Nov 02, 2007 · Heat treatment in SF 6 results in surface roughness smoothing of the Al 2 O 3 layer and produces a smooth and well-defined interface between Al 2 O 3 and the Al-substrate. The surface morphology can be very important in electrical applications as the lack of surface irregularities is expected to reduce electron field emission under a high electric field and therefore minimize corona losses or partial discharges in GITL applications.Get price

Passivation mechanisms in cryogenic Sulfr hexafluoride/O2 etching process

Oct 17, 2003 · The fact that the passivating layer is completely removed when the wafer temperature is reset to +30 °C was confirmed by such an experiment. The passivating layer cannot be properly rebuilt by pure oxygen plasma. Some additional SF 6 should be injected with oxygen to a 30 s duration plasma to recreate it completely (O 2 /SF 6 ratio of about 90%). This result is of interest for multi-step processes when etching must be started with a preliminary etched trench profile.Get price
