  • Patent number: 11374004
    Abstract: Stacked transistor structures and methods of forming same. In an embodiment, a stacked transistor structure has a wide central pedestal region and at least one relatively narrower channel region above and/or below the wider central pedestal region. The upper and lower channel regions are configured with a non-planar architecture, and include one or more semiconductor fins, nanowires, and/or nanoribbons. The top and bottom channel regions may be configured the same or differently, with respect to shape and/or semiconductor materials. In some cases, an outermost sidewall of one or both the top and/or bottom channel region structures, is collinear with an outermost sidewall of the wider central pedestal region. In some such cases, the outermost sidewall of the top channel region structure is collinear with the outermost sidewall of the bottom channel region structure. Top and bottom transistor structures (NMOS/PMOS) may be formed using the top and bottom channel region structures.

  • Patent number: 11367722
    Abstract: A nanowire transistor structure has a first device region with a first body of semiconductor material having a first cross-sectional shape. A second device region has a second body with a second cross-sectional shape different from the first cross-sectional shape. The first device section is vertically above or below the second device section with the bodies extending horizontally between a source and drain. A first gate structure is wrapped around the first body and a second gate structure is wrapped around the second body. Differences in the geometries of the nanowires can be used to optimize performance in the first device section independently of the second device section.

  • Publication number: 20220183080
    Abstract: A method performed by a wireless device. The method may be understood to be for handling a random access procedure in a wireless communications network via a network node. The wireless device operates in the wireless communications network. The wireless device refrains, after having sent a first message to the network node requesting random access and having received a first random access response message from the network node, from stopping a timer. The timer is for a time window for receiving the random access response message. The wireless device also continues monitoring both: a) a radio channel for further random access response messages from the network node addressed to a temporary identifier, and b) the radio channel, addressed to a temporary identifier specifically addressing the wireless device.

  • Patent number: 11348916
    Abstract: Stacked transistor structures having a conductive interconnect between upper and lower transistors. In an embodiment, the interconnect is formed by first provisioning a protective layer over an area to be protected (gate dielectric or other sensitive material) of upper transistor, and then etching material adjacent and below the protected area to expose an underlying contact point of lower transistor. A metal is deposited into the void created by the etch to provide the interconnect. The protective layer is resistant to the etch process and is preserved in the structure, and in some cases may be utilized as a work-function metal. In an embodiment, the protective layer is formed by deposition of reactive semiconductor and metal material layers which are subsequently transformed into a work function metal or work function metal-containing compound. A remnant of unreacted reactive semiconductor material may be left in structure and collinear with protective layer.

  • Publication number: 20210305098
    Abstract: Integrated circuitry comprising stacked first and second transistor structures. One of a source, drain or gate terminal of an upper-level transistor structure is coupled to one of a source, drain or gate terminal of a lower-level transistor structure through an asymmetrical interconnect having a lateral width that increases within a dimension parallel to a semiconductor sidewall of the upper-level transistor by a greater amount than in an orthogonal dimension. A dielectric material between the upper and lower transistor structures may be anisotropically etched asymmetrically by orienting a workpiece to be non-orthogonal to a reactive ion flux. Varying an angle between the reactive ion flux and a plane of the second transistor during an etch of the dielectric material may ensure an etched opening is of sufficient bottom dimension to expose a terminal of the lower-level transistor even if not perfectly aligned with the second transistor structure.

  • Publication number: 20210297918
    Abstract: A network-based method allows a network to optimize its control of radio resource usage by directing connected and idle mode User Equipment (UEs) (10) to another network node, e.g. a neighbor cell, having a better duty cycle, or by configuring the UEs to use another frequency band served by the same network node or a different network node. Signaling its duty cycle budget to the UEs allows the UEs to optimize their idle mode operation by performing cell re-selection to a network node which has a better duty cycle budget.

  • Patent number: 11128405
    Abstract: According to an aspect, a wireless device identifies system frame numbers (SFNs) that are used for wireless transmissions that use a broadcast channel (BCH) transmission time interval (TTI), where frequency hopping cycles (FHCs) are not aligned with a cycle of the SFNs. The wireless device receives FH information indicating how the FHC used for wireless transmissions relates to the SFN cycle and identifies an SFN timing for the wireless transmissions based on the FH information.

A calibration object is conveyed through the food processing machine by the conveyor and scanned. A controller, with a memory, is in communication with the cutting device and the conveyor such that the controller can track position of the cutting device as the cutting device is moved into alignment with the calibration object and store calibration values on the memory corresponding to the movement of the cutting device into alignment with the calibration object. The controller is configured to calibrate movement of the cutting device relative to the workpiece based on the digital image of the workpiece and the calibration values to thereafter accurately cut the workpiece.
