Abstract: Occurrence of short-channel characteristics and parasitic capacitance of a MOSFET on a SOI substrate is prevented. A sidewall having a stacked structure obtained by sequentially stacking a silicon oxide film and a nitride film is formed on a side wall of a gate electrode on the SOI substrate. Subsequently, after an epitaxial layer is formed beside the gate electrode, and then, the nitride film is removed. Then, an impurity is implanted into an upper surface of the semiconductor substrate with using the gate electrode and the epitaxial layer as a mask, so that a halo region is formed in only a region of the upper surface of the semiconductor substrate which is right below a vicinity of both ends of the gate electrode.

Abstract: Integrated circuit structures having backside self-aligned penetrating conductive source or drain contacts, and methods of fabricating integrated circuit structures having backside self-aligned penetrating conductive source or drain contacts, are described. For example, an integrated circuit structure includes a sub-fin structure over a vertical stack of horizontal nanowires. An epitaxial source or drain structure is laterally adjacent and coupled to the vertical stack of horizontal nanowires. A conductive source or drain contact is laterally adjacent to the sub-fin structure and extends into the epitaxial source or drain structure. The conductive source or drain contact does not extend around the epitaxial source or drain structure.

Abstract: Embodiments of the disclosure are in the field of advanced integrated circuit structure fabrication and, in particular, 10 nanometer node and smaller integrated circuit structure fabrication and the resulting structures. In an example, an integrated circuit structure includes a fin. A gate dielectric layer is over the top of the fin and laterally adjacent the sidewalls of the fin. A gate electrode is over the gate dielectric layer over the top of the fin and laterally adjacent the sidewalls of the fin. First and second semiconductor source or drain regions are adjacent the first and second sides of the gate electrode, respectively. First and second trench contact structures are over the first and second semiconductor source or drain regions, respectively, the first and second trench contact structures both comprising a U-shaped metal layer and a T-shaped metal layer on and over the entirety of the U-shaped metal layer.

Abstract: On a semiconductor substrate having an SOI region and a bulk silicon region formed on its upper surface, epitaxial layers are formed in source and drain regions of a MOSFET formed in the SOI region, and no epitaxial layer is formed in source and drain regions of a MOSFET formed in the bulk silicon region. By covering the end portions of the epitaxial layers with silicon nitride films, even when diffusion layers are formed by implanting ions from above the epitaxial layers, it is possible to prevent the impurity ions from being implanted down to a lower surface of a silicon layer.
