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.

In another embodiment, a method for forming a dielectric material on a substrate is provided which includes depositing a metal oxide layer substantially free of silicon on a substrate surface, exposing the metal oxide layer to a nitridation process, and exposing the substrate to an anneal process.
摘要:
This invention is embodied in an improved process for growing high-quality silicon dioxide layers on silicon by subjecting it to a gaseous mixture of nitrous oxide (N2O) and ozone (O3). The presence of O3 in the oxidizing ambiance greatly enhances the oxidation rate compared to an ambiance in which N2O is the only oxidizing agent. In addition to enhancing the oxidation rate of silicon, it is hypothesized that the presence of O3 interferes with the growth of a thin silicon oxynitride layer near the interface of the silicon dioxide layer and the unreacted silicon surface which makes oxidation in the presence of N2O alone virtually self-limiting. The presence of O3 in the oxidizing ambiance does not impair oxide reliability, as is the case when silicon is oxidized with N2O in the presence of a strong, fluorine-containing oxidizing agent such as NF3 or SF6.

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 (5) atmospheres to twenty-five (25) atmospheres N20 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.

摘要:
An electrical device including a shallow junction with a variable concentration profile gradation of dopants. The junction is suitable for forming source and drain regions in MOS transistors, especially where a contact or interconnect is intended to engage the source and drain regions. The variable concentration profile gradation of dopants helps to maintain proper threshold voltage levels and reduces reverse bias current leakage. The electrical device includes a semiconductor substrate having a top surface, a gate region overlapping a portion of the semiconductor substrate, and a source/drain region disposed within the semiconductor substrate. The source/drain region includes an inner portion and an outer portion, wherein the inner portion extends from the top surface of the semiconductor substrate to a bottom periphery and does not underlap the gate region, and the outer portion extends from the bottom periphery of the inner portion and underlaps the gate region. An electrical insulation layer is situated upon the gate region and overlaps the source/drain region.
