摘要:
The present invention is generally directed to a method of forming titanium nitride layers. In one illustrative embodiment, the method includes forming a layer of titanium nitride by performing a deposition process, performing an anneal process on the layer of titanium nitride in a chlorine scavenging ambient to define an annealed layer of titanium nitride, and, prior to exposing the annealed layer of titanium nitride to an oxygen-containing ambient, forming a cap layer on the annealed layer of titanium nitride. In another illustrative embodiment, the method includes performing a chemical vapor deposition process in a first process chamber to form a layer of titanium nitride above a semiconducting substrate, transferring the substrate to a second process chamber, performing an anneal process on the layer of titanium nitride in a chlorine scavenging ambient within the second process chamber to produce an anneal layer of titanium nitride, and, prior to exposing the annealed layer of titanium nitride to an oxygen-containing ambient, forming a cap layer on the annealed layer of titanium nitride in the second process chamber.

The invention includes methods of forming layers comprising epitaxial silicon. In one implementation, an opening is formed within a first material received over a monocrystalline material. Opposing sidewalls of the opening are lined with a second material, with monocrystalline material being exposed at a base of the second material-lined opening. A silicon-comprising layer is epitaxially grown from the exposed monocrystalline material within the second material-lined opening. At least a portion of the second material lining is in situ removed. Other aspects and implementations are contemplated.

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.

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.

A method of forming a capacitor includes forming a conductive metal first electrode layer over a substrate, with the conductive metal being oxidizable to a higher degree at and above an oxidation temperature as compared to any degree of oxidation below the oxidation temperature. At least one oxygen containing vapor precursor is fed to the conductive metal first electrode layer below the oxidation temperature under conditions effective to form a first portion oxide material of a capacitor dielectric region over the conductive metal first electrode layer. At least one vapor precursor is fed over the first portion at a temperature above the oxidation temperature effective to form a second portion oxide material of the capacitor dielectric region over the first portion. The oxide material of the first portion and the oxide material of the second portion are common in chemical composition. A conductive second electrode layer is formed over the second portion oxide material of the capacitor dielectric region.

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.

The invention includes constructions having two dielectric layers over a conductively-doped semiconductive material. One of the dielectric layers contains aluminum oxide, and the other contains a metal oxide other than aluminum oxide (such metal oxide can be, for example, one or more of hafnium oxide, tantalum oxide, titanium oxide and zirconium oxide). The layer containing aluminum oxide is between the layer containing metal oxide and the conductively-doped semiconductive material. The invention includes capacitor devices having one electrode containing conductively-doped silicon and another electrode containing one or more metals and/or metal compounds. At least two dielectric layers are formed between the two capacitor electrodes, with one of the dielectric layers containing aluminum oxide and the other containing a metal oxide other than aluminum oxide. The invention also includes methods of forming capacitor constructions.

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.
