Decomposition of Sulfr hexafluoride in an RF Plasma Environment

Sulfr hexafluoride exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η sf 6 was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W). The addition of oxygen to the reactor re-duced the electron density and, thus, reduced the dis-sociation of SF 6 and inhibited the production ofGet price

Myth About gaz sf6 Gas In Electrical Equipment

Apr 12, 2021 · This is just the UK, Sulfr hexafluoride stays in the atmosphere for a minimum 1000 years where as CO2 100 years. Sulfr hexafluoride is on the increase the US expect a 6.2% increase over the next 6 years. gaz sf6 might not damage the Ozone but it will accelerate Global Warming given the fact that it stays in the atmosphere longer can cause more damage over a longer period of time.Get price

Low temperature etching of Si in high density plasma using sf6 gas/O2

Low temperature etching of Si with SF 6 has been studied, using a DECR system and a special Helicon type plasma source. In contrast to the current understanding of low temperature etching, we did not observe a “freezing” of the lateral etching reaction, but obtained isotropic etch profiles, even at temperatures below −120° C. Anisotropic etch profiles are obtained by an addition of O 2.Get price

A Study of Parameters Related to the Etch Rate for a Dry Etch

AbstractIntroductionMaterials and MethodsResults and DiscussionConclusionAcknowledgmentsThe characteristics of the dry etching of :H thin films for display devices using Sulfr hexafluoride/O2 and NF3/O2 were investigated using a dual-frequency capacitively coupled plasma reactive ion etching (CCP-RIE) system. The investigation was carried out by varying the RF power ratio (13.56 MHz/2 MHz), pressure, and gas flow ratio. For the :H film, the etch rates obtained using NF3/O2 were higher than those obtained using insulating gas/O2 under various process conditions. The relationships between the etch rates and the usual monitoring parameters—the optical emission spectroscopy (OES) intensity of atomic fluorine (685.1 nm and 702.89 nm) and the voltages and —were investigated. The OES intensity data indicated a correlation between the bulk plasma density and the atomic fluorine density. The etch rate was proportional to the product of the OES intensity of atomic fluorine and the square root of the voltages on the assumption that the velocity of the reactive fluorine was proportional to the square root...Get price
