Passivation mechanisms in cryogenic sf 6/O2 etching process

Oct 15, 2003 · Passivation mechanisms of Si trenches involved in SF 6 /O 2 cryogenic plasma etching were investigated in order to better control the process and avoid defects. Trench sidewalls and profiles were ex situ characterized geometrically by SEM and chemically by spatially resolved XPS experiments.Get price

Plasma etching of Si and SiO2 in gaz sf6–O2 mixtures: Journal of

Jun 04, 1998 · With an SF 6 ‐O 2 mixture in the absence of silicon, the final reaction products are F 2, SOF 4, and SO 2 F 2. The product distribution was unaffected by small SiO 2 substrates. When Si is etched, SiF 4 is the only stable silicon‐containing etch product and SOF 2 is formed in oxygen‐poor mixtures. Rapid etch rates (≳10 4 Å/min for Si) can be obtained with a high selectivity in favor of silicon (Si:SiO 2 ≳40:1); thus SF 6 ‐O 2 mixtures may represent an attractive alternative toGet price

Decomposition of gaz sf6 in an RF Plasma Environment

sf6 gas clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η sf6 gas exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η insulating gas 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 oxygenGet price

Heats of Adsorption of Pure sf6 gas and CO2 on Silicalite Pellets

Dec 05, 2000 · Isosteric heats of adsorption of pure gaz sf6 and CO2 were calorimetrically measured on a sample of pelletized silicalite with alumina binder. The corresponding heats of adsorption on a sample of gamma alumina were also measured. The silicalite is a homogeneous adsorbent for these gases, but the presence of the binder in the pelletized silicalite sample introduces an energetic heterogeneity forGet price

Decomposition of sf 6 in an RF plasma environment.

Sulfur hexafluoride (SFd)-contained gas is a common pollutant emitted during the etching process used in the semiconductor industry. This study demonstrated the application of radio-frequency (RF) plasma in the decomposition of sf 6. The decomposition fraction of gaz sf6 [etagaz sf6 (C (in)-C (out))/C (in) x 100%] and the mole fraction profile of the products were investigated as functions of input power and feed O2/sf6 gas ratio in an SiO2 reactor.Get price
