FABRICATION OF GATE-ALL-AROUND INTEGRATED CIRCUIT STRUCTURES HAVING COMMON METAL GATES AND HAVING GATE DIELECTRICS WITH A DIPOLE LAYER

Gate-all-around integrated circuit structures having common metal gates and having 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 a PMOS gate stack having a P-type conductive layer on a first gate dielectric including a high-k dielectric layer on a first dipole material layer. A second gate stack is over the second vertical arrangement of horizontal nanowires, the second gate stack an NMOS gate stack having the P-type conductive layer on a second gate dielectric including the high-k dielectric layer on a second dipole material layer.
