  • Publication number: 20190148290
    Abstract: Exemplary embodiments for various via pillar structures include one or more first conductors in a first interconnect layer of a semiconductor stack interconnected with one or more second conductors in a second interconnect layer of the semiconductor stack. The one or more first conductors and/or the one or more second conductors within the first interconnect layer and the second interconnect layer, respectively, can traverse multiple directions. In some situations, this allows multiple interconnections to be utilized to interconnect the one or more first conductors and the one or more second conductors. These multiple interconnections can reduce resistance between the one or more first conductors and the one or more second conductors thereby improving performance of signals flowing between the one or more first conductors and the one or more second conductors.
