Abstract: Integrated circuit structures having anti-fuse structures, and methods of fabricating integrated circuit structures having anti-fuse structures, are described. For example, an integrated circuit structure includes a first vertical stack of horizontal nanowires. A first gate structure is over the first vertical stack of horizontal nanowires, the first gate structure including a first gate dielectric and a first gate electrode completely surrounding a channel region of each nanowire of the first vertical stack of horizontal nanowires. The integrated circuit structure also includes a second vertical stack of horizontal nanowires. A second gate structure is over the second vertical stack of horizontal nanowires, the second gate structure including a second gate dielectric and a second gate electrode only partially surrounding a channel region of each nanowire of the second vertical stack of horizontal nanowires.

Abstract: Integrated circuit structures having a buried power rail are described. In an example, an integrated circuit structure includes a device layer including a drain structure having an uppermost surface. A buried power rail is within the device layer and is neighboring the drain structure, the buried power rail having an uppermost surface below the uppermost surface of the drain structure. A top-side power rail is vertically over the buried power rail, the top-side power rail having a bottommost surface above the uppermost surface of the drain structure. A conductive structure is directly coupling the top-side power rail to the buried power rail.

Abstract: Embodiments herein relate to systems, apparatuses, or processes for forming a decoupling capacitor within a multilayer die using hybrid bonding.

Other embodiments may be described and/or claimed.

Abstract: Embodiments described herein may be related to apparatuses, processes, and techniques related to well biasing using a buried power rail (BPR) within a circuit structure. Embodiments include using a silicide material between the BPR and a well, where the silicide material provides ohmic contact between the BPR and the well.

Abstract: Embodiments described herein may be related to apparatuses, processes, and techniques related to forming capacitors using lines in a bond pad layer within hybrid bonding techniques of two separate dies and then coupling those dies. In embodiments, these techniques may involve using dummy bond pads, where the width of these dummy bond pads are smaller than that of active bond pads, to create a pattern to serve as a capacitor structure. Other embodiments may be described and/or claimed.

Abstract: Disclosed herein are IC structures with decoupling capacitors based on dummy TSV plates provided in a support structure (e.g., a substrate, a die, a wafer, or a chip). An example decoupling capacitor includes first and second capacitor plates and a capacitor insulator between them. Each capacitor plate is a different blind, plate-like opening in the support structure, the openings at least partially filled with one or more conductive materials. The capacitor plate openings are referred to herein as “dummy TSV plates” because they may be fabricated while providing regular TSV openings in the support structure. Such decoupling capacitors may be better suited for high-speed microprocessor applications than conventional off-chip decoupling capacitors and may advantageously allow integrating on-chip decoupling capacitors with an ample amount of capacitive decoupling, limited or no additional processing steps on top of regular TSV processing, and in areas that may not have been used otherwise.

Abstract: Disclosed herein are transistor arrangements with trench contacts that have two parts—a first trench contact and a second trench contact—stacked over one another. Such transistor arrangements may be fabricated by forming a first trench contact over a source or drain contact of a transistor, recessing the first trench contact, forming the second trench contact over the first trench contact, and, finally, forming a gate contact that is electrically isolated from, while being self-aligned to, the second trench contact. Such a fabrication process may provide improvements in terms of increased edge placement error margin, cost-efficiency, and device performance, compared to conventional approaches to forming trench and gate contacts. The conductive material of the first trench contact may also be deposited over the gate electrodes of transistors, forming a gate strap, to advantageously reduce gate resistance.

Abstract: Transistor arrangements fabricated by forming a metal gate cut as an opening that is non-selective to the gate sidewalls are disclosed. The etch process may be used to provide a power rail if the opening is at least partially filled with an electrically conductive material. Once an electrically conductive material has been deposited within the opening to form a power rail, recessing such a material in portions of the power rail that face gate stacks of various transistors may provide further improvements in terms of reduced parasitic capacitance. A mask for a trench contact to be used to electrically couple the power rail to a S/D region of a transistor may be used as a mask when the electrically conductive material of the power rail is recessed to realize a via that is self-aligned to the trench contact.

Abstract: A method for forming a dielectric-isolated bulk fin field-effect transistor (finFET) device includes forming a second isolation layer over a first structure including multiple partially exposed fins and horizontal areas including a first isolation layer. The second isolation layer is removed from horizontal areas of a first portion of the first structure. An oxide layer is formed under the fins of the first portion of the first structure. The second isolation layer is removed in order to expose the partially exposed fins and horizontal areas of the first structure to form a second structure, on which gate regions are formed.
