  • Patent number: 9466664
    Abstract: Methods and structures for forming uniaxially-strained, nanoscale, semiconductor bars from a biaxially-strained semiconductor layer are described. A spatially-doubled mandrel process may be used to form a mask for patterning dense, narrow trenches through the biaxially-strained semiconductor layer. The resulting slicing of the biaxially-strained layer enhances carrier mobility and can increase device performance.

  • Patent number: 9425051
    Abstract: The substrate is provided with a first semiconducting area partially covered by a first masking pattern to define a protected surface and an open surface. A continuous layer of silicon-germanium is deposited in non-selective manner on the first semiconducting area and on the first gate pattern. The continuous silicon-germanium layer forms an interface with the first semiconducting area. A diffusion/condensation annealing is performed to make the germanium atoms diffuse from the silicon-germanium layer to the open surface of the first semiconducting area. The masking pattern is a gate stack of the transistor or is used to define the shape of the gate stack in an electrically insulating layer so as to form a self-aligned gate stack with the source and drain areas.
