摘要： Semiconductor devices having germanium active layers with underlying diffusion barrier layers are described. For example, a semiconductor device includes a gate electrode stack disposed above a substrate. A germanium active layer is disposed above the substrate, underneath the gate electrode stack. A diffusion barrier layer is disposed above the substrate, below the germanium active layer. A junction leakage suppression layer is disposed above the substrate, below the diffusion barrier layer. Source and drain regions are disposed above the junction leakage suppression layer, on either side of the gate electrode stack.

摘要： Nanowire-based gate all-around transistor devices having one or more active nanowires and one or more inactive nanowires are described herein. Methods to fabricate such devices are also described. One or more embodiments of the present invention are directed at approaches for varying the gate width of a transistor structure comprising a nanowire stack having a distinct number of nanowires. The approaches include rendering a certain number of nanowires inactive (i.e. so that current does not flow through the nanowire), by severing the channel region, burying the source and drain regions, or both. Overall, the gate width of nanowire-based structures having a plurality of nanowires may be varied by rendering a certain number of nanowires inactive, while maintaining other nanowires as active.
