    Abstract: Gate-all-around integrated circuit structures having depopulated channel structures, and methods of fabricating gate-all-around integrated circuit structures having depopulated channel structures, are described. For example, an integrated circuit structure includes a first vertical arrangement of nanowires and a second vertical arrangement of nanowires above a substrate, the first vertical arrangement of nanowires having a greater number of active nanowires than the second vertical arrangement of nanowires, and the first and second vertical arrangements of nanowires having co-planar uppermost nanowires. The integrated circuit structure also includes a first vertical arrangement of nanoribbons and a second vertical arrangement of nanoribbons above the substrate, the first vertical arrangement of nanoribbons having a greater number of active nanoribbons than the second vertical arrangement of nanoribbons, and the first and second vertical arrangements of nanoribbons having co-planar uppermost nanoribbons.

    Abstract: A MOS antifuse with an accelerated dielectric breakdown induced by a void or seam formed in the electrode. In some embodiments, the programming voltage at which a MOS antifuse undergoes dielectric breakdown is reduced through intentional damage to at least part of the MOS antifuse dielectric. In some embodiments, damage may be introduced during an etchback of an electrode material which has a seam formed during backfilling of the electrode material into an opening having a threshold aspect ratio. In further embodiments, a MOS antifuse bit-cell includes a MOS transistor and a MOS antifuse. The MOS transistor has a gate electrode that maintains a predetermined voltage threshold swing, while the MOS antifuse has a gate electrode with a void accelerated dielectric breakdown.
