    摘要: Gate-all-around integrated circuit structures having germanium nanowire channel structures, and methods of fabricating gate-all-around integrated circuit structures having germanium nanowire channel structures, are described. For example, an integrated circuit structure includes a vertical arrangement of horizontal nanowires above a fin, each of the nanowires including germanium, and the fin including a defect modification layer on a first semiconductor layer, a second semiconductor layer on the defect modification layer, and a third semiconductor layer on the second semiconductor layer. A gate stack is around the vertical arrangement of horizontal nanowires. A first epitaxial source or drain structure is at a first end of the vertical arrangement of horizontal nanowires, and a second epitaxial source or drain structure is at a second end of the vertical arrangement of horizontal nanowires.

    摘要: Embodiments disclosed herein include forksheet transistor devices having a dielectric or a conductive spine. For example, an integrated circuit structure includes a dielectric spine. A first transistor device includes a first vertical stack of semiconductor channels spaced apart from a first edge of the dielectric spine. A second transistor device includes a second vertical stack of semiconductor channels spaced apart from a second edge of the dielectric spine. An N-type gate structure is on the first vertical stack of semiconductor channels, a portion of the N-type gate structure laterally between and in contact with the first edge of the dielectric spine and the first vertical stack of semiconductor channels. A P-type gate structure is on the second vertical stack of semiconductor channels, a portion of the P-type gate structure laterally between and in contact with the second edge of the dielectric spine and the second vertical stack of semiconductor channels.
