    摘要: In one embodiment, a method for forming a morphologically stable dielectric material is provided which includes exposing a substrate to a hafnium precursor, a silicon precursor and an oxidizing gas to form hafnium silicate material during a chemical vapor deposition (CVD) process and subsequently and optionally exposing the substrate to a post deposition anneal, a nitridation process and a thermal annealing process. In some examples, the hafnium and silicon precursors used during a metal-organic CVD (MOCVD) process are alkylamino compounds, such as tetrakis(diethylamino)hafnium (TDEAH) and tris(dimethylamino)silane (Tris-DMAS). In another embodiment, other metal precursors may be used to form a variety of metal silicates containing tantalum, titanium, aluminum, zirconium, lanthanum or combinations thereof.

    摘要: Embodiments of the invention provide methods for depositing materials on substrates during vapor deposition processes, such as atomic layer deposition (ALD). In one embodiment, a chamber contains a substrate support with a receiving surface and a chamber lid containing an expanding channel formed within a thermally insulating material. The chamber further includes at least one conduit coupled to a gas inlet within the expanding channel and positioned to provide a gas flow through the expanding channel in a circular direction, such as a vortex, a helix, a spiral, or derivatives thereof. The expanding channel may be formed directly within the chamber lid or formed within a funnel liner attached thereon. The chamber may contain a retaining ring, an upper process liner, a lower process liner or a slip valve liner. Liners usually have a polished surface finish and contain a thermally insulating material such as fused quartz or ceramic. In an alternative embodiment, a deposition system contains a catalytic water vapor generator connected to an ALD chamber.

    摘要: In one embodiment, a method for forming a dielectric material is provided which includes exposing a substrate sequentially to a metal-containing precursor and an oxidizing gas to form metal oxide (e.g., HfOx) during an ALD process and subsequently exposing the substrate to an inert plasma process and a thermal annealing process. Generally, the metal oxide contains hafnium, tantalum, titanium, aluminum, zirconium, lanthanum or combinations thereof. In one example, the inert plasma process contains argon and is free of nitrogen, while the thermal annealing process contains oxygen. In another example, an ALD process to form a metal oxide includes exposing the substrate sequentially to a metal precursor and an oxidizing gas containing water vapor formed by a catalytic water vapor generator. In an alternative embodiment, a method for forming a dielectric material is provide which includes exposing a substrate to a deposition process to form a metal oxide layer and subsequently exposing the substrate to a nitridation plasma process and a thermal annealing process to form metal oxynitride (e.g., HfOxNy).

    摘要: Embodiments of the invention provide methods for depositing dielectric materials on substrates during vapor deposition processes, such as atomic layer deposition (ALD). In one example, a method includes sequentially exposing a substrate to a hafnium precursor and an oxidizing gas to deposit a hafnium oxide material thereon. In another example, a hafnium silicate material is deposited by sequentially exposing a substrate to the oxidizing gas and a process gas containing a hafnium precursor and a silicon precursor. The oxidizing gas usually contains water vapor formed by flowing a hydrogen source gas and an oxygen source gas through a water vapor generator. In another example, a method includes sequentially exposing a substrate to the oxidizing gas and at least one precursor to deposit hafnium oxide, zirconium oxide, lanthanum oxide, tantalum oxide, titanium oxide, aluminum oxide, silicon oxide, aluminates thereof, silicates thereof, derivatives thereof or combinations thereof.
