    Abstract: A semiconductor package including a package substrate with an upper surface, a controller, and a die stack. The controller and the die stack are at the upper surface. The die stack includes a shingled sub-stack of semiconductor dies, a reverse-shingled sub-stack of semiconductor dies, and a bridging chip. The bridging chip is bonded between the shingled sub-stack and the reverse-shingled sub-stack, and has an internal trace. A first wire segment is bonded between the controller and a first end of the bridging chip, and a second wire segment is bonded between a second end of the bridging chip and each semiconductor die of the shingled sub-stack. The internal trace electrically couples the first and second wire segments. Additionally, a third wire segment is bonded between the controller and each semiconductor die of the reverse-shingled sub-stack.

    Abstract: Semiconductor devices with three-dimensional trace matching features, and related systems and methods, are disclosed herein. In some embodiments, an exemplary semiconductor device includes at least one semiconductor die and a redistribution layer disposed over the at least one semiconductor die and extending across a longitudinal plane. The redistribution layer includes first and second traces each electrically coupled to the at least one semiconductor die. The first trace is disposed in a first travel path included in a first effective path length. The second trace is disposed in a second travel path different from the first travel path. The second the second travel path includes at least one segment at a non-right, non-zero angle such that the at least one segment is neither parallel nor perpendicular to the longitudinal plane. Further, the second travel path is included in a second effective path length equal to the first path length.
