    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 atmosphere to 25 atmosphere 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.

    Abstract: In a capacitor forming method, a first capacitor electrode is formed over a substrate. A high K oxygen containing capacitor dielectric layer is formed over the first capacitor electrode. A first annealing of the high K capacitor dielectric layer is conducted at a temperature of at least about 500.degree. C. in a substantially non-oxidizing atmosphere. After the first annealing, second annealing the high K capacitor dielectric layer occurs at a temperature of less than or equal to about 500.degree. C. in an oxidizing atmosphere. A second capacitor electrode is formed over the high K oxygen containing capacitor dielectric layer, preferably after the second annealing. In another considered implementation, the capacitor dielectric layer is annealed in multiple steps including at least two different temperatures. A second capacitor electrode is formed over the high K oxygen containing dielectric layer, with the substrate not being exposed to a gaseous oxygen containing atmosphere at a temperature of greater than about 500.degree. C. between the capacitor dielectric layer formation and formation of the second capacitor electrode. The invention also contemplates dielectric layer processing apart from capacitor formation, and the fabrication of DRAM circuitry.

    Abstract: A method of fabricating a semiconductor device includes depositing a dielectric film and subjecting the dielectric film to a wet oxidation in a rapid thermal process chamber. The technique can be used, for example, in the formation of various elements in an integrated circuit, including gate dielectric films as well as capacitive elements. The tight temperature control provided by the RTP process allows the wet oxidation to be performed quickly so that the oxidizing species does not diffuse significantly through the dielectric film and diffuse into an underlying layer. In the case of capacitive elements, the technique also can help reduce the leakage current of the dielectric film without significantly reducing its capacitance.
