    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: 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).
