    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 apparatuses and 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.
