  • Patent number: 10538609
    Abstract: A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition. The pre-vulcanization composition comprises soluble sulfur with high S8 ring structure that is catalytically broken by a zinc dithiocarbamate. Surfactants present in the pre-vulcanization composition wets synthetic polyisoprene particles and permeates small sized sulfur and accelerator molecules into the interior of these particles thereby pre-vulcanizing the particles. The degree of pre-vulcanization is verified by isopropanol index test. The latex emulsion has post-vulcanization composition with accelerators that crosslink inter-particle region during post vulcanization cure cycle. The dipped synthetic polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds in TEM and zinc segregation at the boundaries or original particles by electron microprobe analysis.

    Abstract: Methods and apparatus for reducing particles in a gas delivery system are provided herein. In some embodiments, a method of fabricating a gas distribution apparatus, such as a gas distribution plate or nozzle, for a semiconductor process chamber includes providing a gas distribution apparatus having one or more apertures adapted to flow a gas therethrough. A slurry is flowed through the one or more apertures to remove a damaged surface from sidewalls of the plurality of apertures. In some embodiments, the gas distribution apparatus may be oxidized before or after flowing the slurry through the one or more apertures. In some embodiments, the gas distribution apparatus may be conditioned by providing RF power to the gas distribution plate for a desired period of time.
