  • Patent number: 12183739
    Abstract: Integrated circuitry comprising a ribbon or wire (RoW) transistor stack within which the transistors have different threshold voltages (Vt). 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 Vt within the stack. After diffusion, the metal oxide may be stripped as sacrificial, or retained.

  • Patent number: 11814908
    Abstract: A formation tester tool assembly includes a seal member mounted on rigid stabilizer that contacts a borehole wall separately from the seal member, so that seal exposure to a stabilization load that presses the tool against the borehole wall is limited or reduced by contact engagement of the stabilizer with the borehole wall. The stabilizer is provided by a hydraulically actuated probe piston reciprocally movable relative to a tool body on which it is mounted. The seal member is in some embodiments movable relative to the probe piston, for example being configured for hydraulic actuation to sealingly engage the borehole wall while the tool body is stabilized by action of the probe piston.

  • Patent number: 11522060
    Abstract: Embodiments herein describe techniques for a thin-film transistor (TFT) above a substrate. The transistor includes a contact electrode having a conductive material above the substrate, an epitaxial layer above the contact electrode, and a channel layer including a channel material above the epitaxial layer and above the contact electrode. The channel layer is in contact at least partially with the epitaxial layer. A conduction band of the channel material and a conduction band of a material of the epitaxial layer are substantially aligned with an energy level of the conductive material of the contact electrode. A bandgap of the material of the epitaxial layer is smaller than a bandgap of the channel material. Furthermore, a gate electrode is above the channel layer, and separated from the channel layer by a gate dielectric layer. Other embodiments may be described and/or claimed.

  • Patent number: 11469766
    Abstract: Digital-to-analog converters (DACs) having a multiple-gate (multi-gate) transistor-like structure are disclosed herein. The DAC structures have a similar structure to a transistor (e.g., a MOSFET) and include source and drain regions. However, instead of employing only one gate between the source and drain regions, multiple distinct gates are employed. Each distinct gate can represent a bit for the DAC and can include different gate lengths to enable providing different current values, and thus, unique outputs. Further, N number of inputs can be applied to N number of gates employed by the DAC. The DAC structure may be configured such that the longest gate controls the LSB of the DAC and the shortest gate controls the MSB, or vice versa. In some cases, the multi-gate DAC employs high-injection velocity materials that enable compact design and routing, such as InGaAs, InP, SiGe, and Ge, to provide some examples.

  • Patent number: 11430943
    Abstract: A magnetic tunneling junction (MTJ) memory device including a free and fixed (reference) magnet between first and second electrodes, and a synthetic antiferromagnet structure (SAF) structure between the fixed magnet and one of the electrodes. The SAF structure includes a magnetic skyrmion. Two magnetic skyrmions within a SAF structure may have opposing polarity. A SAF structure may further include a coupling layer between two magnetic layers, as well as interface layers separated from the coupling layer by one of the magnetic layers. The coupling layer may have a spin-orbit coupling effect on the magnetic layers that is of a sign opposite that of the interface layers, for example to promote formation of the magnetic skyrmions.

  • Patent number: 11386951
    Abstract: A MTJ device includes a free (storage) magnet and fixed (reference) magnet between first and second electrodes, and a programmable booster between the free magnet and one of the electrodes. The booster has a magnetic material layer. The booster may further have an interface layer that supports the formation of a skyrmion spin texture, or a stable ferromagnetic domain, within the magnetic material layer. A programming current between two circuit nodes may be employed to set a position of the skyrmion or magnetic domain within the magnetic material layer to be more proximal to, or more distal from, the free magnet. The position of the skyrmion or magnetic domain to the MTJ may modulate TMR ratio of the MTJ device. The TMR ratio modulation may be employed to discern more than two states of the MTJ device. Such a multi-level device may, for example, be employed to store 2 bits/cell.
