    摘要: Known techniques to improve metal-oxide-semiconductor field effect transistor (MOSFET) performance is to add a high stress dielectric layer to the MOSFET. The high stress dielectric layer introduces stress in the MOSFET that causes electron mobility drive current to increase. This technique increases process complexity, however, and can degrade PMOS performance. Embodiments of the present invention create dislocation loops in the MOSFET substrate to introduce stress and implants nitrogen in the substrate to control the growth of the dislocation loops so that the stress remains beneath the channel of the MOSFET.

    摘要: A nanowire device having a plurality of internal spacers and a method for forming said internal spacers are disclosed. In an embodiment, a semiconductor device comprises a nanowire stack disposed above a substrate, the nanowire stack having a plurality of vertically-stacked nanowires, a gate structure wrapped around each of the plurality of nanowires, defining a channel region of the device, the gate structure having gate sidewalls, a pair of source/drain regions on opposite sides of the channel region; and an internal spacer on a portion of the gate sidewall between two adjacent nanowires, internal to the nanowire stack. In an embodiment, the internal spacers are formed by depositing spacer material in dimples etched adjacent to the channel region. In an embodiment, the dimples are etched through the channel region. In another embodiment, the dimples are etched through the source/drain region.
