  • Patent number: 9978588
    Abstract: Approaches for protecting a semiconductor device (e.g., a fin field effect transistor device (FinFET)) using a nitride spacer are provided. Specifically, a nitride spacer is formed over an oxide and a set of fins of the FinFET device to mitigate damage during subsequent processing. The nitride spacer is deposited before the block layers to protect the oxide on top of a set of gates in an open area of the FinFET device uncovered by a photoresist. The oxide on top of each gate will be preserved throughout all of the block layers to provide hardmask protection during subsequent source/drain epitaxial layering. Furthermore, the fins that are open and uncovered by the photoresist or the set of gates remain protected by the nitride spacer. Accordingly, fin erosion caused by amorphization of the fins exposed to resist strip processes is prevented, resulting in improved device yield.

  • Publication number: 20150214345
    Abstract: Approaches for isolating source and drain regions in an integrated circuit (IC) device (e.g., a metal-oxide-semiconductor field-effect transistor (MOSFET)) are provided. Specifically, the device comprises a gate structure formed over a substrate, a source and drain (S/D) embedded within the substrate adjacent the gate structure, and a liner layer (e.g., silicon-carbon) between the S/D and the substrate. In one approach, the liner layer is formed atop the S/D as well. As such, the liner layer formed in the junction prevents dopant diffusion from the source/drain.

  • Publication number: 20150076654
    Abstract: Approaches for providing enlarged fin tips for a set of fins of a fin field effect transistor device (FinFET) are disclosed. Specifically, approaches are provided for patterning a hardmask formed over a substrate; forming a set of fin tips from the substrate using a first etch; and forming a set of fins from the substrate using a second etch, wherein each of the set of fin tips has a width greater than a most narrow section of each of the set of fins. Each of the fin tips has a tapered profile that enlarges towards a top end thereof to compensate for erosion losses during processing.
