  • Publication number: 20200232089
    Abstract: A semiconductor device and a method of fabricating the device are disclosed. The method of forming a metal layer includes: placing a substrate in a sputtering chamber; forming a first metal sub-layer on the substrate by performing a magnetron sputtering process; and forming a second metal sub-layer on the first metal sub-layer by performing another magnetron sputtering process and concurrently introducing a heated gas stream in the sputtering chamber, wherein the first metal sub-layer and the second metal sub-layer together constitute the metal layer and are each formed of aluminum doped with copper. The metal layer resulting from this method contains uniformly-sized small crystal grains separated from one another by minimal gaps between their grain boundaries. This imparts to the metal layer high surface flatness with fewer undesired bumps and hence good appearance, resulting in an increase in its yield.

  • Publication number: 20200228287
    Abstract: A communication method, a communications apparatus, and a device are described. The communication operation carried out by a terminal includes receiving BWP indication information sent by a network device. The BWP indication information instructs the terminal to activate a BWP and/or deactivate a BWP. The communication operation further includes sending BWP feedback information to the base station. The BWP feedback information indicates that the terminal successfully received the BWP indication information. In this way, in the event of a data transmission failure because the UE cannot receive or cannot correctly parse the BWP indication information, the UE and the base station communicating by using different BWPs can be avoided, thereby improving communication quality.

  • Publication number: 20200218676
    Abstract: Examples herein relate to polling for input/output transactions of a network interface or a storage device, or any peripheral device. Some examples monitor clock cycles spent checking for a presence of input/output (I/O) events and processing I/O events and monitor clock cycles spent checking for presence of I/O events without completing an I/O event. Central processing unit (CPU) core utilization can be based on clock cycles spent checking for a presence of I/O events and processing I/O events and clock cycles spent checking for presence of I/O events without completion of an I/O event. For example, if core utilization is below a threshold, frequency of the core can be reduced for performing polling of I/O events. If core utilization is at or above the threshold, frequency of the core can be increased used to performing polling of I/O events.
