  • Patent number: 9768262
    Abstract: Carbon-doped germanium stressor regions are formed in an nFET device region of a germanium substrate and at a footprint of a functional gate structure. The carbon-doped germanium stressor regions are formed by an epitaxial growth process utilizing monomethylgermane (GeH3—CH3) as the carbon source. The carbon-doped germanium stressor regions that are provided yield more strain in less volume since a carbon atom is much smaller than a silicon atom.

  • Patent number: 9305883
    Abstract: A low resistance contact to a finFET source/drain can be achieved by forming a defect free surface on which to form such contact. The fins of a finFET can be exposed to epitaxial growth conditions to increase the bulk of semiconductive material in the source/drain. Facing growth fronts can merge or can form unmerged facets. A dielectric material can fill voids within the source drain region. A trench spaced from the finFET gate can expose the top portion of faceted epitaxial growth on fins within said trench, such top portions separated by a smooth dielectric surface. A silicon layer selectively formed on the top portions exposed within the trench can be converted to a semiconductor-metal layer, connecting such contact with individual fins in the source drain region.
