Interconnect structures, packaged semiconductor devices, and methods of packaging semiconductor devices are disclosed. In some embodiments, an interconnect structure includes dielectric layers, a conductive layer disposed in the dielectric layers, and a via layer disposed in the dielectric layers proximate the conductive layer. An underball metallization (UBM) layer is disposed in the dielectric layers proximate the via layer. A first connector coupling region is disposed in the via layer and the UBM layer. A via layer portion of the first connector coupling region is coupled to a first contact pad in the conductive layer. A second connector coupling region is disposed in the UBM layer. The second connector coupling region is coupled to a conductive segment in the UBM layer and the via layer. The second connector coupling region is coupled to a second contact pad in the conductive layer by the conductive segment.
