  • Patent number: 8367547
    Abstract: The method comprises affixing a thin sheet of crystal (8) onto metal (6) of same type as the sheet but amorphous or of small grain size, deposited in trenches of a substrate (1) to form interconnect lines for example. Annealing progressively imposes the crystalline structure of the sheet onto the lines. When the crystal (8) is removed, highly conductive crystalline lines are obtained since the grains thereof have been greatly enlarged.

  • Patent number: 8324690
    Abstract: A composite dielectric layer including a tensile stressed nitride layer over an oxide layer serves the dual function of acting as an SMT (stress memorization technique) film while an annealing operation is carried out and then remains partially intact as it is patterned to further serve as an RPO film during a subsequent silicidation process. The composite dielectric layer covers part of a semiconductor substrate that includes a gate structure. The tensile stressed nitride layer protects the oxide layer and alleviates oxide damage during a pre-silicidation PAI (pre-amorphization implant) process. Portions of the gate structure and the semiconductor substrate not covered by the composite dielectric layer include amorphous portions that include the PAI implanted dopant impurities. A silicide material is disposed on the gate structure and portions of the semiconductor substrate not covered by the composite dielectric layer.
