  • STACKED VIA STRUCTURES AND METHODS FOR FORMING THE SAME
    Publication number: 20240145379
    Abstract: Methods and semiconductor devices are provided. A method includes determining a location of a polyimide opening (PIO) corresponding to an under-bump metallization (UBM) feature in a die. The die includes a substrate and an interconnect structure over the substrate. The method also includes determining a location of a stacked via structure in the interconnect structure based on the location of the PIO. The method further includes forming, in the interconnect structure, the stacked via structure comprising at most three stacked contact vias at the location of the PIO.

  • Jitter-based transmission control method
    Patent number: 9432297
    Abstract: A jitter-based transmission control method is disclosed. In the jitter-based transmission control method, several packets are sent applying a current congestion window size by at least one sender device through a network switch device. An immediate jitter ratio of the network switch device is calculated by the sender device. An average jitter ratio of the network switch device is updated by the sender device according to the immediate jitter ratio and the current congestion window size. The current congestion window size is reduced when the immediate jitter ratio or the updated average jitter ratio is positive and larger than a queued threshold over the current congestion window size, such that the packets are sent applying the reduced current congestion window size.
