  • Publication number: 20060035473
    Abstract: A method and apparatus for preventing N2O from becoming super critical during a high pressure oxidation stage within a high pressure oxidation furnace are disclosed. The method and apparatus utilize a catalyst to catalytically disassociate N2O as it enters the high pressure oxidation furnace. This catalyst is used in an environment of between five atmospheres and 25 atmospheres N2O and a temperature range of 600° to 750° C., which are the conditions that lead to the N2O going super critical. By preventing the N2O from becoming super critical, the reaction is controlled that prevents both temperature and pressure spikes. The catalyst can be selected from the group of noble transition metals and their oxides. This group can comprise palladium, platinum, iridium, rhodium, nickel, silver, and gold.

  • Publication number: 20060001161
    Abstract: An electrical contact includes a non-conductive spacer surrounding conductive plug material along the full height of the contact. The spacer inhibits oxide and other diffusion through the contact. In the illustrated embodiment, the contact includes metals or metal oxides which are resistant to oxidation, and additional conductive barrier layers. The contact is particularly useful in integrated circuits which include high dielectric constant materials.

  • Publication number: 20050147751
    Abstract: A deposition method includes positioning a substrate within a deposition chamber defined at least in part by chamber walls. At least one of the chamber walls comprises a chamber surface having a plurality of purge gas inlets to the chamber therein. A process gas is provided over the substrate effective to deposit a layer onto the substrate. During such providing, a material adheres to the chamber surface. Reactive purge gas is emitted to the deposition chamber from the purge gas inlets effective to form a reactive gas curtain over the chamber surface and away from the substrate, with such reactive gas reacting with such adhering material. Further implementations are contemplated.

  • Publication number: 20050026458
    Abstract: The invention includes methods of forming hafnium-containing materials, such as, for example, hafnium oxide. In one aspect, a semiconductor substrate is provided, and first reaction conditions are utilized to form hafnium-containing seed material in a desired crystalline phase and orientation over the substrate. Subsequently, second reaction conditions are utilized to grow second hafnium-containing material over the seed material. The second hafnium-containing material is in a crystalline phase and/or orientation different from the crystalline phase and orientation of the hafnium-containing seed material. The second hafnium-containing material can be, for example, in an amorphous phase. The seed material is then utilized to induce a desired crystalline phase and orientation in the second hafnium-containing material. The invention also includes capacitor constructions utilizing hafnium-containing materials, and circuit assemblies comprising the capacitor constructions.
