Abstract: Stacked transistor structures and methods of forming same. In an embodiment, a stacked transistor structure has a wide central pedestal region and at least one relatively narrower channel region above and/or below the wider central pedestal region. The upper and lower channel regions are configured with a non-planar architecture, and include one or more semiconductor fins, nanowires, and/or nanoribbons. The top and bottom channel regions may be configured the same or differently, with respect to shape and/or semiconductor materials. In some cases, an outermost sidewall of one or both the top and/or bottom channel region structures, is collinear with an outermost sidewall of the wider central pedestal region. In some such cases, the outermost sidewall of the top channel region structure is collinear with the outermost sidewall of the bottom channel region structure. Top and bottom transistor structures (NMOS/PMOS) may be formed using the top and bottom channel region structures.

Abstract: An embodiment includes an apparatus comprising: a fin structure on a substrate, the fin structure including fin top and bottom portions, a channel including a majority carrier, and an epitaxial (EPI) layer; an insulation layer including insulation layer top and bottom portions adjacent the fin top and bottom portions; wherein (a) the EPI layer comprises one or more of group IV and III-V materials, (b) the fin bottom portion includes a fin bottom portion concentration of dopants of opposite polarity to the majority carrier, (c) the fin top portion includes a fin top portion concentration of the dopants less than the fin bottom portion concentration, (d) the insulation layer bottom portion includes an insulation layer bottom portion concentration of the dopants, and (e) the insulation layer top portion includes an insulation top layer portion concentration greater than the insulation bottom portion concentration. Other embodiments are described herein.

Abstract: Ge and III-V channel semiconductor devices having maximized compliance and free surface relaxation and methods of fabricating such Ge and III-V channel semiconductor devices are described. For example, a semiconductor device includes a semiconductor fin disposed above a semiconductor substrate. The semiconductor fin has a central protruding or recessed segment spaced apart from a pair of protruding outer segments along a length of the semiconductor fin. A cladding layer region is disposed on the central protruding or recessed segment of the semiconductor fin. A gate stack is disposed on the cladding layer region. Source/drain regions are disposed in the pair of protruding outer segments of the semiconductor fin.
