发明名称 Conductive routings in integrated circuits using under bump metallization
摘要 An integrated circuit structure includes a first conductive layer and an under bump metallization layer over the first conductive layer. The first conductive layer has a first conductive region and a second conductive region electrically isolated from the first conductive region. The under bump metallization layer has a first conductive area and a second conductive area electrically isolated from the first conductive area, the first conductive area substantially located over the first conductive region and the second conductive area substantially located over the second conductive region. At least one of the first conductive area or the first conductive region includes a first protrusion extending toward the second conductive area or second conductive region, respectively. Conductive vias connect the first conductive region to the second conductive area and connect the second conductive region to the first conductive area, and the vias include at least one via connected to the first protrusion.
