  • Patent number: 9984940
    Abstract: A scaled dielectric stack interlayer, compatible with subsequent high temperature processing with good electrical transport & reliability properties is provided. A method for forming a conformal aSi:H passivation layer on a semiconductor device is described. A patterned semiconductor wafer is placed in in a process chamber with a first layer formed thereon and a second layer formed thereon, the first layer and the second layer being two different materials Next, a SixH(2x+2) based deposition up to a temperature of 400 degrees Celsius is used on the first layer and the second layer thereby forming a conformal aSi:H passivating layer is formed at a higher rate of deposition on the first layer selectively and a lower rate of deposit on the second layer.

  • Publication number: 20160225853
    Abstract: A semiconductor-carbon alloy layer is formed on the surface of a semiconductor substrate, which may be a commercially available semiconductor substrate such as a silicon substrate. The semiconductor-carbon alloy layer is converted into at least one graphene layer during a high temperature anneal, during which the semiconductor material on the surface of the semiconductor-carbon alloy layer is evaporated selective to the carbon atoms. As the semiconductor atoms are selectively removed and the carbon concentration on the surface of the semiconductor-carbon alloy layer increases, the remaining carbon atoms in the top layers of the semiconductor-carbon alloy layer coalesce to form a graphene layer having at least one graphene monolayer. Thus, a graphene layer may be provided on a commercially available semiconductor substrate having a diameter of 200 mm or 300 mm.

    Abstract: A semiconductor structure includes a III-V monocrystalline layer and a germanium surface layer. An interlayer is formed directly between the III-V monocrystalline layer and the germanium surface layer from a material selected to provide stronger nucleation bonding between the interlayer and the germanium surface layer than nucleation bonding that would be achievable directly between the III-V monocrystalline layer and the germanium surface layer such that a continuous, relatively defect-free germanium surface layer is provided.
