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.

Abstract: A client-side dynamic multi-routing power distribution system of an optical terminal equipment integrates the Power over Ethernet, dynamic multi-routing power distribution and power management technologies to dispatch power to the optical terminal equipment from a home gateway to meet power demands of the off-premise optical terminal equipment and to greatly reduce the cost for laying power lines for the off-premise FTTx optical terminal equipment, thereby expanding the coverage of optical fiber broadband service. The client-side dynamic multi-routing power distribution system includes (1) a network signal processing and DC power supply module of the home gateway for dispatching power to the remote FTTx optical terminal equipment through a telecom line at a network interface; (2) a network signal processing and DC powered module of the FTTx optical terminal equipment for handling multi-routing power distribution and dynamic load balancing from a plurality of home gateways.
