Wakeup signaling resource occasions
Methods, systems, and devices for wireless communications are described. Some wireless communications systems support user equipment (UEs) achieving power savings by operating in a connected discontinuous reception (C-DRX) mode. The systems may additionally utilize wakeup signals for further power savings at a UE. For example, a UE may be configured with a wakeup signal resource configuration (e.g., a first search space configuration) for monitoring for wakeup signals while operating in a low power mode. This first search space configuration may be different from a second search space configuration for the UE operating in an active mode. When in a low power mode, the UE may monitor for wakeup signals according to the wakeup signal resource configuration. If the UE receives a wakeup signal in a wakeup signal resource defined by the configuration, the UE may initiate a wakeup procedure and transition to the active mode for data transmission and reception. |

Network interface device that sets an ECN-CE bit in response to detecting congestion at an internal bus interface
A network device includes a Network Interface Device (NID) and multiple servers. Each server is coupled to the NID via a corresponding PCIe bus. The NID has a network port through which it receives packets. The packets are destined for one of the servers. The NID detects a PCIe congestion condition regarding the PCIe bus to the server. Rather than transferring the packet across the bus, the NID buffers the packet and places a pointer to the packet in an overflow queue. If the level of bus congestion is high, the NID sets the packet's ECN-CE bit. When PCIe bus congestion subsides, the packet passes to the server. The server responds by returning an ACK whose ECE bit is set. The originating TCP endpoint in turn reduces the rate at which it sends data to the destination server, thereby reducing congestion at the PCIe bus interface within the network device. |

A first liner is formed in the openings of the first region, and first contacts are formed in the first region on the first liner. The first region is blocked with a second mask to remove the sacrificial material from the second region. The second mask is removed from the first region, and the sacrificial liner is removed from the second region. A second liner is formed in the openings of the second region, and second contacts are formed in the second region. |

Wafer uniting method
A wafer uniting method includes a thermocompression bonding step of causing a thermocompression bonding sheet having a size comparable to or greater than a size and a shape of a wafer and a front surface of the wafer to face each other, and pressing them against each other while applying heat to thermocompression bond the thermocompression bonding sheet to the front surface of the wafer. The thermocompression bonding sheet thermocompression bonded to the wafer in the thermocompression bonding step includes at least a first thermocompression bonding sheet and a second thermocompression bonding sheet. |

Inorganic light emitting diode (ILED) assembly via direct bonding
Embodiments relate to transferring dies or other electronic components from a carrier substrate to a target substrate of a device as part of chip assembly for the device. Bonding material is applied to selected dies on a carrier substrate by direct boning, or to corresponding die transfer locations on a target substrate. The carrier substrate is then brought into contact with the target substrate to transfer each of the selected dies to the carrier substrate. Dies can also be directly bonded to the target substrate even in the presence of other die in situ (e.g., from a previous bonding cycle), hence, enables more than one direct bond cycle to be carried out for a target substrate. As such, multi-color (RGB) display elements can be assembled in stages (e.g., separate bonding cycles) in a flexible manner to provide redundancy or to replace inoperative LED dies. |
