  • Publication number: 20080042105
    Abstract: The present invention is; (a) a process for stabilizing a cyclotetrasiloxane, such as 1,3,5,7-tetramethylcyclotetrasiloxane, against polymerization used in a chemical vapor deposition process for silicon oxides in electronic material fabrication comprising providing an effective amount of an antioxidant polymerization inhibitor to such cyclotetrasiloxane; and (b) a composition of a cyclotetrasiloxane, such as 1,3,5,7-tetramethylcyclotetrasiloxane, stabilized against polymerization used in a chemical vapor deposition process as a precursor for silicon oxides in electronic material fabrication, comprising; such cyclotetrasiloxane and an antioxidant.

  • Publication number: 20070224829
    Abstract: A mixture and a method comprising same for etching a dielectric material from a layered substrate are disclosed herein. Specifically, in one embodiment, there is provided a mixture for etching a dielectric material in a layered substrate comprising: a fluorocarbon gas, a fluorine-containing oxidizer gas selected from the group consisting of a hypofluorite, a fluoroperoxide, a fluorotrioxide, and combinations thereof; and optionally an inert diluent gas. The mixture of the present invention may be contacted with a layered substrate comprising a dielectric material under conditions sufficient to form active species that at least partially react with and remove at least a portion of the dielectric material.

  • Publication number: 20070049774
    Abstract: This invention is directed to an improvement in a process for producing high-purity fluorinated peroxides typically formed by the reaction of a carbonyl fluoride with a hypofluorite. The improvement resides in a simplified process for the synthesis and recovery of high purity fluorinated high purity peroxide product and comprises the steps: (a) reacting the carbonyl fluoride with the hypofluorite under conditions such that a gaseous reaction product comprised of the fluorinated peroxide and unreacted carbonyl fluoride which is essentially free of unreacted hypofluorite is formed; (b) removing unreacted carbonyl fluoride and by products from the gaseous reaction product under gas phase conditions thereby generating a gaseous product stream containing the fluorinated peroxide; and then, (c) collecting the fluorinated peroxide from step (b) in gas phase.

  • Publication number: 20060252904
    Abstract: The present invention is; (a) a process for stabilizing a cyclotetrasiloxane, such as 1,3,5,7-tetramethylcyclotetrasiloxane, against polymerization used in a chemical vapor deposition process for silicon oxides in electronic material fabrication comprising providing an effective amount of a free radical scavenger polymerization inhibitor to such cyclotetrasiloxane; and (b) a composition of a cyclotetrasiloxane, such as 1,3,5,7-tetramethylcyclotetrasiloxane, stabilized against polymerization used in a chemical vapor deposition process as a precursor for silicon oxides in electronic material fabrication, comprising; such cyclotetrasiloxane and a free radical scavenger polymerization inhibitor.

  • Publication number: 20050011859
    Abstract: A mixture and a method comprising same for etching a dielectric material from a layered substrate are disclosed herein. Specifically, in one embodiment, there is provided a mixture for etching a dielectric material in a layered substrate comprising an unsaturated oxygenated fluorocarbon. The mixture of the present invention may be contacted with a layered substrate comprising a dielectric material under conditions sufficient to at least partially react with and remove at least a portion of the dielectric material. In another embodiment of the present invention, there is provided a method for making an unsaturated oxygenated fluorocarbon.
