  • Publication number: 20250212441
    Abstract: Contacts to n-type and p-type source/drain regions of field-effect transistors comprise a doped contact metal layer positioned between the fill metal and the source/drain regions. The doped contact metal layer comprises a metal and a semiconductor dopant and is formed by reactive sputtering. By varying the concentration of a reactive gas comprising the dopant in the sputtering environment, the atomic composition of the dopant in the doped contact metal layer can vary as the doped contact metal layer is formed. The presence of doped contact metal layers in source/drain contacts can provide for thermally stable low resistance source/drain contacts by inhibiting dopant diffusion from the source/drain regions to the contact metal. In some embodiments, a non-doped contact metal layer can be positioned between the fill metal and the doped contact metal layer.

  • Publication number: 20250133822
    Abstract: Integrated circuitry comprising a ribbon or wire (RoW) transistor stack within which the transistors have different threshold voltages (Vt). In some examples, a gate electrode of the transistor stack may include only one workfunction metal. A metal oxide may be deposited around one or more channels of the transistor stack as a solid-state source of a metal oxide species that will diffuse toward the channel region(s). As diffused, the metal oxide may remain (e.g., as a silicate, or hafnate) in close proximity to the channel region, thereby altering the dipole properties of the gate insulator material. Different channels of a transistor stack may be exposed to differing amounts or types of the metal oxide species to provide a range of Vt within the stack. After diffusion, the metal oxide may be stripped as sacrificial, or retained.
