SYMMETRICAL SUBSTRATE FOR SEMICONDUCTOR PACKAGING

An integrated circuit package that includes symmetrical redistribution structures on either side of a core substrate is provided. In an embodiment, a device comprises a core substrate, a first redistribution structure comprising one or more layers, a second redistribution comprising one or more layers, a first integrated circuit die, and a set of external conductive features. The core substrate is disposed between the first redistribution structure and the second redistribution structure, the first integrated circuit die is disposed on the first distribution structure on the opposite side from the core substrate; and the set of external conductive features are disposed on a side of the second redistribution structure opposite the core substrate. The first redistribution structure and second redistribution structure have symmetrical redistribution layers to each other with respect to the core substrate.
