    Abstract: Integrated circuit structures having differentiated source or drain structures are described. In an example, an integrated circuit structure includes first, second and third pluralities of horizontally stacked nanowires or fins, and first, second and third gate stacks. A first epitaxial source or drain structure is between the first plurality of horizontally stacked nanowires or fin and the second plurality of horizontally stacked nanowires or fin, the first epitaxial source or drain structure having a lateral width and a composition. A second epitaxial source or drain structure is between the second plurality of horizontally stacked nanowires or fin and the third plurality of horizontally stacked nanowires or fin, the second epitaxial source or drain structure having the composition of the first epitaxial source or drain structure, and the second epitaxial source or drain structure having a lateral width less than the lateral width of the first epitaxial source or drain structure.

    Abstract: Backside contact structures include etch selective materials to facilitate backside contact formation. An integrated circuit structure includes a frontside contact region, a device region below the frontside contact region, and a backside contact region below the device region. The device region includes a transistor. The backside contact region includes a first dielectric material under a source or drain region of the transistor, a second dielectric material laterally adjacent to the first dielectric material and under a gate structure of the transistor. A non-conductive spacer is between the first and second dielectric materials. The first and second dielectric materials are selectively etchable with respect to one another and the spacer. The backside contact region may include an interconnect feature that, for instance, passes through the first dielectric material and contacts a bottom side of the source/drain region, and/or passes through the second dielectric material and contacts the gate structure.
