  • Publication number: 20080102011
    Abstract: A substrate processing apparatus comprises a process chamber and an effluent treatment apparatus comprising a hydrogenation reactor, scrubber, combustor, and a controller to operate the process chamber and effluent treatment apparatus. In the hydrogenation reactor, hydrogen-containing gas is used to treat chamber effluent to form a hydrogenated effluent comprising hydrogen chloride gas. A scrubber sprays water through the hydrogenated effluent to dissolve the hydrogen chloride gas. An oxygen-containing gas is added to the treated effluent during a combustion step to further abate the effluent.

  • Publication number: 20080081130
    Abstract: A substrate processing apparatus exposes a substrate in a process zone of a process chamber to a plasma of a precursor gas comprising a hydrocarbon gas to deposit carbon-doped silicon on the substrate. An effluent comprising unreacted precursor gas and byproducts from the carbon-doped silicon deposition process is exhausted from the process zone and passed into an effluent treatment zone of an effluent treatment reactor. An additive gas comprising an oxygen-containing gas is added to the effluent treatment zone and a plasma is formed of the effluent and additive gas to treat the effluent to reduce the content of unreacted precursor gas and byproduct in the effluent.

  • Patent number: 5861346
    Abstract: Silicon carbide films and microcomponents are grown on silicon substrates at surface temperatures between 900 K and 1700 K via C.sub.60 precursors in a hydrogen-free environment. Selective crystalline silicon carbide growth can be achieved on patterned silicon-silicon oxide samples. Patterned SiC films are produced by making use of the high reaction probability of C.sub.60 with silicon at surface temperatures greater than 900 K and the negligible reaction probability for C.sub.60 on silicon dioxide at surface temperatures less than 1250 K.
