Embodiments disclosed herein include semiconductor devices with Schottky diodes in a back end of line stack. In an embodiment, a semiconductor device comprises a semiconductor layer, where transistor devices are provided in the semiconductor layer, and a back end stack over the semiconductor layer. In an embodiment, a diode is in the back end stack. In an embodiment, the diode comprises a first electrode, a semiconductor region over the first electrode, and a second electrode over the semiconductor region. In an embodiment, a first interface between the first electrode and the semiconductor region is an ohmic contact, and a second interface between the semiconductor region and the second electrode is a Schottky contact.

Compositional engineering of Schottky diode

Integrated circuitry interconnect structures comprising a first metal and a graphene cap over a top surface of the first metal. Within the interconnect structure an amount of a second metal, nitrogen, or silicon is greater proximal to an interface of the graphene cap. The presence of the second metal, nitrogen, or silicon may improve adhesion of the graphene to the first metal and/or otherwise improve electromigration resistance of a graphene capped interconnect structure. The second metal, nitrogen, or silicon may be introduced into the first metal during deposition of the first metal, or during a post-deposition treatment of the first metal. The second metal, nitrogen, or silicon may be introduced prior to, or after, capping the first metal with graphene.

In one embodiment, a resonator device includes a substrate comprising a piezoelectric material and a set of electrodes on the substrate. The electrodes are in parallel and a width of the electrodes is equal to a distance between the electrodes. The RF resonator device further includes a set of switches, with each switch coupled to a respective electrode.

Low resistance and reduced reactivity approaches for fabricating contacts, and semiconductor structures having low resistance metal contacts, are described. In an example, an integrated circuit structure includes a semiconductor structure above a substrate. A gate electrode is over the semiconductor structure, the gate electrode defining a channel region in the semiconductor structure. A first semiconductor source or drain structure is at a first end of the channel region at a first side of the gate electrode.

Gate dielectrics for complementary metal oxide semiconductors transistors and methods of fabrication

A transistor includes a body of semiconductor material, where the body has laterally opposed body sidewalls and a top surface. A gate structure contacts the top surface of the body. A source region contacts a first one of the laterally opposed body sidewalls and a drain region contacts a second one of the laterally opposed body sidewalls. A first isolation region is under the source region and has a top surface in contact with a bottom surface of the source region. A second isolation region is under the drain region and has a top surface in contact with a bottom surface of the drain region. Depending on the transistor configuration, a major portion of the inner-facing sidewalls of the first and second isolation regions contact respective sidewalls of either a subfin structure (e.g., FinFET transistor configurations) or a lower portion of a gate structure (e.g., gate-all-around transistor configuration).

An integrated circuit interconnect structure includes a metallization level above a first device level. The metallization level includes an interconnect structure coupled to the device structure, a conductive cap including an alloy of a metal of the interconnect structure and either silicon or germanium on an uppermost surface of the interconnect structure. A second device level above the conductive cap includes a transistor coupled with the conductive cap. The transistor includes a channel layer including a semiconductor material, where at least one sidewall of the conductive cap is co-planar with a sidewall of the channel layer. The transistor further includes a gate on a first portion of the channel layer, where the gate is between a source region and a drain region, where one of the source or the drain region is in contact with the conductive cap.

Self-aligned interconnect structures and methods of fabrication

Transistor structures with monocrystalline metal chalcogenide channel materials are formed from a plurality of template regions patterned over a substrate. A crystal of metal chalcogenide may be preferentially grown from a template region and the metal chalcogenide crystals then patterned into the channel region of a transistor. The template regions may be formed by nanometer-dimensioned patterning of a metal precursor, a growth promoter, a growth inhibitor, or a defected region. A metal precursor may be a metal oxide suitable, which is chalcogenated when exposed to a chalcogen precursor at elevated temperature, for example in a chemical vapor deposition process.

Methods for fabricating metallization stacks with one or more self-aligned staggered metal lines, and related semiconductor devices, are disclosed. Methods and devices are based on providing a spacer material conformal to bottom metal lines of a first layer of a metallization stack. By carefully designing parameters of the deposition process, the spacer material may be deposited in such a manner that, for each pair of adjacent bottom metal lines of the first layer, an opening in the spacer material is formed in a layer above the bottom metal lines (i.e., in the second layer of the metallization stack), the opening being substantially equidistant to the adjacent bottom metal lines of the first layer. Top metal lines are formed by filling the openings with an electrically conductive material, resulting in the top metal lines being self-aligned and staggered with respect to the bottom metal lines.

Metallization stacks with self-aligned staggered metal lines

Disclosed herein are capacitors including built-in electric fields, as well as related devices and assemblies. In some embodiments, a capacitor may include a top electrode region, a bottom electrode region, and a dielectric region between and in contact with the top electrode region and the bottom electrode region, wherein the dielectric region includes a perovskite material, and the top electrode region has a different material structure than the bottom electrode region.

Capacitors with built-in electric fields

Integrated circuitry comprising a ribbon or wire (RoW) transistor stack within which the transistors have different threshold voltages (V). In some examples, a gate electrode of the transistor stack may include only one workfunction metal. A metal oxide may be deposited around one or more channels of the transistor stack as a solid-state source of a metal oxide species that will diffuse toward the channel region(s). As diffused, the metal oxide may remain (e.g., as a silicate, or hafnate) in close proximity to the channel region, thereby altering the dipole properties of the gate insulator material. Different channels of a transistor stack may be exposed to differing amounts or types of the metal oxide species to provide a range of Vwithin the stack. After diffusion, the metal oxide may be stripped as sacrificial, or retained.

Ribbon or wire transistor stack with selective dipole threshold voltage shifter

An integrated circuit (IC) structure in a memory device is described. In an example, the IC structure includes a memory cell including a bitline (BL) extending along a first direction and a channel extending along a second direction above and diagonal to the BL. In the example, a wordline (WL) extends in a third direction perpendicular to the first direction of the BL and intersects with the channel to control a current in the channel along a gated channel length. In some examples, the channel is electrically coupled on a first side to a storage capacitor via a storage node contact (SNC) and on a second side to the BL via a bit line contact (BLC) located on an underside or backside of the channel.
