Abstract: Self-aligned gate endcap (SAGE) architectures without fin end gaps, and methods of fabricating self-aligned gate endcap (SAGE) architectures without fin end gaps, are described. In an example, an integrated circuit structure includes a semiconductor fin having a cut along a length of the semiconductor fin. A gate endcap isolation structure has a first portion parallel with the length of the semiconductor fin and is spaced apart from the semiconductor fin. The gate endcap isolation structure also has a second portion in a location of the cut of the semiconductor fin and in contact with the semiconductor fin.

Abstract: Integrated circuit structures having dual stress gates are described. For example, an integrated circuit structure includes a first vertical stack of horizontal nanowires, and a second vertical stack of nanowires laterally spaced apart from the first vertical stack of horizontal nanowires. An NMOS gate electrode is over the first vertical stack of horizontal nanowires, the NMOS gate electrode having a tensile layer extending from a top to a bottom of the first vertical stack of horizontal nanowires. A PMOS gate electrode is over the second vertical stack of horizontal nanowires, the PMOS gate electrode having a compressive layer extending from a top to a bottom of the second vertical stack of horizontal nanowires. The tensile layer of the NMOS gate electrode is not included in the PMOS gate electrode.

Abstract: Gate-all-around integrated circuit structures having molybdenum nitride metal gates and gate dielectrics with a dipole layer are described. For example, an integrated circuit structure includes a first vertical arrangement of horizontal nanowires, and a second vertical arrangement of horizontal nanowires. A first gate stack is over the first vertical arrangement of horizontal nanowires, the first gate stack having a P-type conductive layer on a first gate dielectric. The P-type conductive layer includes molybdenum and nitrogen. A second gate stack is over the second vertical arrangement of horizontal nanowires, the second gate stack having an N-type conductive layer on a second gate dielectric.
