    摘要: A conducting plug/contact structure for use with integrated circuit includes a tungsten conducting plug formed in the via with a tungsten-silicon-nitride (WSiYNZ) region providing the interface between the tungsten conducting plug and the substrate (silicon) layer. The interface region is formed providing a nitrided surface layer over the exposed dielectric surfaces and the exposed substrate surface (i.e., exposed by a via in the dielectric layer) prior to the formation of tungsten/tungsten nitride layer filling the via. The structure is annealed forming a tungsten conducting plug with a tungsten-silicon-nitride interface between the conducting plug and the substrate. According to another embodiment, a tungsten nitride surface layer is formed over the nitrided surface layer prior to the formation of a tungsten layer to fill the via. According to another embodiment, a silicon surface layer is applied to the exposed surface of the dielectric layer and to the exposed surface of the substrate prior to formation of the nitrided surface layer. A layer of tungsten, tungsten/tungsten nitride, or tungsten nitride is formed to fill the via. After annealing, a tungsten conducting plug is formed with a tungsten-silicon-nitride interface region with the substrate.

    摘要: High dielectric films of mixed transition metal oxides of titanium and tungsten, or titanium and tantalum, are formed by sequential chemical vapor deposition (CVD) of the respective nitrides and annealing in the presence of oxygen to densify and oxidize the nitrides. The resulting film is useful as a capacitative cell and resists oxygen diffusion to the underlying material, has high capacitance and low current leakage.

    摘要: An embodiment of the instant invention is a method of depositing a TiN-based film over a semiconductor wafer, the method comprising the steps of: substantially simultaneously subjecting the semiconductor wafer to TiCl4, H2, and N2; and subjecting the semiconductor wafer to a plasma, such that the combination of the TiCl4, H2, and N2 and the plasma cause the deposition of a TiN based film to form over the semiconductor wafer. Another embodiment of the instant invention involves additionally subjecting the semiconductor wafer to SiH4 so as to form a TiSixNy film over the semiconductor wafer. Another embodiment of the instant invention involves additionally subjecting the semiconductor wafer to B2H6 so as to form a TiNxBy layer over the semiconductor wafer.
