    摘要: The invention includes an atomic layer deposition method of forming a layer of a deposited composition on a substrate. The method includes positioning a semiconductor substrate within an atomic layer deposition chamber. On the substrate, an intermediate composition monolayer is formed, followed by a desired deposited composition from reaction with the intermediate composition, collectively from flowing multiple different composition deposition precursors to the substrate within the deposition chamber. A material adheres to a chamber internal component surface from such sequentially forming. After such sequentially forming, a reactive gas flows to the chamber which is different in composition from the multiple different deposition precursors and which is effective to react with such adhering material. After the reactive gas flowing, such sequentially forming is repeated. Further implementations are contemplated.

    摘要: Layers of epitaxial silicon are used to protect the tunnel dielectric layer of a floating-gate memory cell from excessive oxidation or removal during the formation of shallow trench isolation (STI) regions. Following trench formation, the layers of epitaxial silicon are grown from silicon-containing layers on opposing sides of the tunnel dielectric layer, thereby permitting their thickness to be limited to approximately one-half of the thickness of the tunnel dielectric layer. The epitaxial silicon may be oxidized prior to filling the trench with a dielectric material or a dielectric fill may occur prior to oxidizing at least the epitaxial silicon covering the ends of the tunnel dielectric layer.

    摘要: An MIS capacitor with low leakage and high capacitance is disclosed. A layer of hemispherical grained polysilicon (HSG) is formed as a lower electrode. Prior to the dielectric formation, the hemispherical grained polysilicon layer may be optionally subjected to a nitridization or anneal process. A dielectric layer of aluminum oxide (Al2O3), or a composite stack of interleaved layers of aluminum oxide and other metal oxide dielectric materials, is fabricated over the hemispherical grained polysilicon layer and after the optional nitridization or anneal process. The dielectric layer of aluminum oxide (Al2O3) or the aluminum oxide composite stack may be optionally subjected to a post-deposition treatment to further increase the capacitance and decrease the leakage current. A metal nitride upper electrode is formed over the dielectric layer or the composite stack by a deposition technique or by atomic layer deposition.

    摘要: The invention includes atomic layer deposition methods of depositing an oxide on a substrate. In one implementation, a substrate is positioned within a deposition chamber. A first species is chemisorbed onto the substrate to form a first species monolayer within the deposition chamber from a gaseous precursor. The chemisorbed first species is contacted with remote plasma oxygen derived at least in part from at least one of O2 and O3 and with remote plasma nitrogen effective to react with the first species to form a monolayer comprising an oxide of a component of the first species monolayer. The chemisorbing and the contacting with remote plasma oxygen and with remote plasma nitrogen are successively repeated effective to form porous oxide on the substrate. Other aspects and implementations are contemplated.
