  • Patent number: 9899529
    Abstract: A method for making a self-aligned vertical nanosheet field effect transistor. A vertical trench is etched in a layered structure including a plurality of layers, using reactive ion etching, and filled, using an epitaxial process, with a vertical semiconductor nanosheet. A sacrificial layer from among the plurality of layers is etched out and replaced with a conductive (e.g., metal) gate layer coated with a high-dielectric-constant dielectric material. Two other layers from among the plurality of layers, one above and one below the gate layer, are doped, and act as dopant donors for a diffusion process that forms two PN junctions in the vertical semiconductor nanosheet.

  • Patent number: 9728502
    Abstract: A method is disclosed to form a metal-oxysilicate diffusion barrier for a damascene metallization. A trench is formed in an Inter Layer Dielectric (ILD) material. An oxysilicate formation-enhancement layer comprising silicon, carbon, oxygen, a constituent component of the ILD, or a combination thereof, is formed in the trench. A barrier seed layer is formed on the oxysilicate formation-enhancement layer comprising an elemental metal selected from a first group of elemental metals in combination with an elemental metal selected from a second group of elemental metals. An elemental metal in the second group is immiscible in copper or an alloy thereof, has a diffusion constant greater than a self-diffusion of copper or an alloy thereof; does not reducing silicon-oxygen bonds during oxysilicate formation; and promotes adhesion of copper or an alloy of copper to the metal-oxysilicate barrier diffusion layer. The structure is then annealed to form a metal-oxysilicate diffusion barrier.
