Abstract: Dual fin endcaps for self-aligned gate edge architectures, and methods of fabricating dual fin endcaps for self-aligned gate edge architectures, are described. In an example, a semiconductor structure includes an I/O device having a first plurality of semiconductor fins disposed above a substrate and protruding through an uppermost surface of a trench isolation layer. A logic device having a second plurality of semiconductor fins is disposed above the substrate and protrudes through the uppermost surface of the trench isolation layer. A gate edge isolation structure is disposed between the I/O device and the logic device. A semiconductor fin of the first plurality of semiconductor fins closest to the gate edge isolation structure is spaced farther from the gate edge isolation structure than a semiconductor fin of the second plurality of semiconductor fins closest to the gate edge isolation structure.

Abstract: Metal resistors and self-aligned gate edge (SAGE) architectures having metal resistors are described. In an example, a semiconductor structure includes a plurality of semiconductor fins protruding through a trench isolation region above a substrate. A first gate structure is over a first of the plurality of semiconductor fins. A second gate structure is over a second of the plurality of semiconductor fins. A gate edge isolation structure is laterally between and in contact with the first gate structure and the second gate structure. The gate edge isolation structure is on the trench isolation region and extends above an uppermost surface of the first gate structure and the second gate structure. A metal layer is on the gate edge isolation structure and is electrically isolated from the first gate structure and the second gate structure.

Abstract: Embodiments of the present invention are directed to dual threshold voltage (VT) channel devices and their methods of fabrication. In an example, a semiconductor device includes a gate stack disposed on a substrate, the substrate having a first lattice constant. A source region and a drain region are formed on opposite sides of the gate electrode. A channel region is disposed beneath the gate stack and between the source region and the drain region. The source region is disposed in a first recess having a first depth and the drain region disposed in a second recess having a second depth. The first recess is deeper than the second recess. A semiconductor material having a second lattice constant different than the first lattice constant is disposed in the first recess and the second recess.
