  • Publication number: 20040089887
    Abstract: A new relatively high-k gate dielectric gate material comprising calcium oxide will reduce leakage from the silicon substrate to the polysilicon gate, prevent boron penetration in p-channel devices, and reduce electron trapping in the dielectric. The surface of a silicon wafer is saturated with hydroxyl groups. A calcium halide, preferably calcium bromide, is heated to a temperature sufficient to achieve atomic layer deposition, and is transported to the silicon wafer. The calcium halide reacts with the hydroxyl groups. Water is added to carry away the resultant hydrogen halide. Gaseous calcium and water are then added to form a calcium oxide gate dielectric, until the desired thickness has been achieved. In an alternative embodiment of the method, the calcium halide is transported to the silicon wafer to react with the hydroxyl groups, followed by transport of gaseous water to the silicon wafer. These two steps are repeated until the desired thickness has been achieved.

  • Patent number: 6673498
    Abstract: A method of forming a reticle is provided. In general, a metal containing material is vaporized through simple vaporization. The metal containing material is condensed on a substrate to form a metal containing layer on the substrate. A patterned photoresist layer is formed over the metal containing layer, defining exposed metal containing layer regions and covered metal containing layer regions. The metal containing layer in the exposed metal containing layer regions is removed from the substrate, while the metal containing layer in the covered metal containing layer regions remains on the substrate to form a metal containing mask. The substrate is plasma etched. The remaining metal containing layer is removed from the substrate.

  • Patent number: 6566262
    Abstract: Embodiments of the invention include a capping layer of alloy material formed over a copper-containing layer, the alloy configured to prevent diffusion of copper through the capping layer. In another embodiment the alloy capping layer is self-aligned to the underlying conducting layer. Specific embodiments include capping layers formed of alloys of copper with materials including but not limited to calcium, strontium, barium, and other alkaline earth metals, as well as materials from other groups, for example, cadmium or selenium. The invention also includes methods for forming an alloy capping layer on a copper-containing conducting structure. One such method includes providing a substrate having formed thereon electrically conducting layer comprised of a copper-containing material and forming an alloy capping layer on the electrically conducting layer. In another method embodiment, forming the alloy capping layer includes forming a self-aligned capping layer over the conducting layer.

  • Patent number: 6511925
    Abstract: In accordance with the invention a high-k gate dielectric is formed by the steps of first forming a silicon oxide layer over a silicon substrate and then exposing the silicon oxide to a flux of low energy plasma containing metal ions which, when inserted into silicon oxide, form a high-k dielectric material suitable for use as a high-k gate dielectric. In one embodiment, the silicon oxide is exposed to a first plasma containing a first species of metal ions and then to a plasma of another species of metal ions which, when inserted into the silicon oxide with the metal ions in the first plasma, further increase the dielectric constant of the silicon oxide.
