Abstract: Nanowire structures having wrap-around contacts are described. For example, a nanowire semiconductor device includes a nanowire disposed above a substrate. A channel region is disposed in the nanowire. The channel region has a length and a perimeter orthogonal to the length. A gate electrode stack surrounds the entire perimeter of the channel region. A pair of source and drain regions is disposed in the nanowire, on either side of the channel region. Each of the source and drain regions has a perimeter orthogonal to the length of the channel region. A first contact completely surrounds the perimeter of the source region. A second contact completely surrounds the perimeter of the drain region.

Abstract: Techniques and mechanisms to provide insulation for a component of an integrated circuit device. In an embodiment, structures of a circuit component are formed in or on a first side of a semiconductor substrate, the structures including a first doped region, a second doped region and a third region between the first doped region and the second doped region. The substrate has formed therein an insulation structure, proximate to the circuit component structures, which is laterally constrained to extend only partially from a location under the circuit component toward an edge of the substrate. In another embodiment, a second side of the substrate—opposite the first side—is exposed by thinning to form the substrate from a wafer. Such thinning enables subsequent back side processing to form a recess in the second side, and to deposit the insulation structure in the recess.

Abstract: Techniques and mechanisms to provide capacitance with a memory cell of an integrated circuit. In an embodiment, a transistor of the memory cell includes structures variously formed in or on a first side of a semiconductor substrate. After processing to form the transistor structures, thinning is performed to expose a second side of the semiconductor substrate, the second side opposite the first side. Processing in or on the exposed second side of the semiconductor substrate is subsequently performed to form in the semiconductor substrate a capacitor that extends to couple to one of the transistor structures. In another embodiment, the capacitor is coupled to accumulate charge based on activation of a channel of the transistor. The capacitor is further coupled to send charge from the memory cell via the second side.

Abstract: Neighboring gate-all-around integrated circuit structures having a conductive contact stressor between epitaxial source or drain regions are described. In an example, a first vertical arrangement of nanowires and a second vertical arrangement of nanowires above a substrate. A first gate stack is over the first vertical arrangement of nanowires. A second gate stack is over the second vertical arrangement of nanowires. First epitaxial source or drain structures are at ends of the first vertical arrangement of nanowires. Second epitaxial source or drain structures are at ends of the second vertical arrangement of nanowires. An intervening conductive contact structure is between neighboring ones of the first epitaxial source or drain structures and of the second epitaxial source or drain structures. The intervening conductive contact structure imparts a stress to the neighboring ones of the first epitaxial source or drain structures and of the second epitaxial source or drain structures.

Abstract: Integrated circuit structures having cavity spacers, and methods of fabricating integrated circuit structures having cavity spacers, are described. For example, an integrated circuit structure includes a sub-fin structure over a stack of nanowires. A gate structure is vertically around the stack of nanowires. An internal gate spacer is between vertically adjacent ones of the nanowires and adjacent to the gate structure. A trench contact structure is laterally adjacent to a side of the gate structure. A cavity spacer is laterally between the gate structure and the trench contact structure.

Abstract: Gate-all-around integrated circuit structures having confined epitaxial source or drain structures, are described. For example, an integrated circuit structure includes a plurality of nanowires above a sub-fin. A gate stack is over the plurality of nanowires and the sub-fin. Epitaxial source or drain structures are on opposite ends of the plurality of nanowires. The epitaxial source or drain structures comprise germanium and boron, and a protective layer comprises silicon, and germanium that at least partially covers the epitaxial source or drain structures. A conductive contact comprising titanium silicide is on the epitaxial source or drain structures.
