  • Patent number: 12243872
    Abstract: A semiconductor device structure, along with methods of forming such, are described. The structure includes a first channel region disposed over a substrate, a second channel region disposed adjacent the first channel region, a gate electrode layer disposed in the first and second channel regions, and a first dielectric feature disposed adjacent the gate electrode layer. The first dielectric feature includes a first dielectric material having a first thickness. The structure further includes a second dielectric feature disposed between the first and second channel regions, and the second dielectric feature includes a second dielectric material having a second thickness substantially less than the first thickness. The second thickness ranges from about 1 nm to about 20 nm.

  • Publication number: 20170117980
    Abstract: A network device is provided, which includes a communication unit and a processing unit. The communication unit is configured to perform a time setting process with a master clock device. The processing unit is coupled to the communication unit and is configured to control the communication unit to perform a time synchronization process for obtaining a time offset of the network device relative to the master clock device. The processing unit is further configured to calculate a processing time elapsed during the time synchronization process and obtain a correction time by calculating the system time of the network device, the time offset and the processing time.

  • Patent number: 9444690
    Abstract: An operating method of a network system includes setting a plurality of first connection ports from among a plurality of connection ports of a first switch as belonging to a first loop group; receiving, through the first switch, a topology change notification; determining, through the first switch, whether the topology change notification is received via one of the first connection ports; and under a condition that the topology change notification is received via one of the first connection ports, outputting, through the first switch, the topology change notification via the other one/ones of the first connection ports, and not via the connection port/ports which do/does not belong to the first loop group. With such operation, broadcasting the topology change notification can be avoided, so as to increase the efficiency, bandwidth, and stability of the network system.
