Abstract: Jumper gates for advanced integrated circuit structures are described. For example, an integrated circuit structure includes a first vertical stack of horizontal nanowire segments. A second vertical stack of horizontal nanowire segments is spaced apart from the first vertical stack of horizontal nanowire segments. A conductive structure is laterally between and in direct electrical contact with the first vertical stack of horizontal nanowire segments and with the second vertical stack of horizontal nanowire segments. A first source or drain structure is coupled to the first vertical stack of horizontal nanowire segments at a side opposite the conductive structure. A second source or drain structure is coupled to the second vertical stack of horizontal nanowire segments at a side opposite the conductive structure.

Abstract: Thin film transistor structures and processes are disclosed that include stacked nanowire bodies to mitigate undesirable short channel effects, which can occur as gate lengths scale down to sub-100 nanometer (nm) dimensions, and to reduce external contact resistance. In an example embodiment, the disclosed structures employ a gate-all-around architecture, in which the gate stack (including a high-k dielectric layer) wraps around each of the stacked channel region nanowires (or nanoribbons) to provide improved electrostatic control. The resulting increased gate surface contact area also provides improved conduction. Additionally, these thin film structures can be stacked with relatively small spacing (e.g., 1 to 20 nm) between nanowire bodies to increase integrated circuit transistor density. In some embodiments, the nanowire body may have a thickness in the range of 1 to 20 nm and a length in the range of 5 to 100 nm.

Abstract: Disclosed are etchstop regions in fins of semiconductor devices, and related methods. A semiconductor device includes a buried region, a fin on the buried region, and a gate formed at least partially around the fin. At least a portion of the fin that borders the buried region includes an etchstop material. The etchstop material includes a doped semiconductor material that has a slower etch rate than that of an intrinsic form of the semiconductor material. A method of manufacturing a semiconductor device includes forming a gate on a fin, implanting part of the fin with dopants configured to decrease an etch rate of the part of the fin, removing at least part of the fin, and forming an epitaxial semiconductor material on a remaining proximal portion of the fin.
