Abstract: Disclosed herein are asymmetric cored integrated circuit (IC) package supports, and related devices and methods. For example, in some embodiments, an IC package support may include a core region having a first face and an opposing second face, a first buildup region at the first face of the core region, and a second buildup region at the second face of the core region. A thickness of the first buildup region may be different than a thickness of the second buildup region. In some embodiments, an inductor may be included in the core region.

Abstract: Disclosed herein are magnetic structures in integrated circuit (IC) package supports, as well as related methods and devices. For example, in some embodiments, an IC package support may include a conductive line and a magnetic structure around a top surface of the conductive line and side surfaces of the conductive line. The magnetic structure may have a tapered shape that narrows toward the conductive line.

Abstract: Semiconductor packages including package substrates having polymer-derived ceramic cores are described. In an example, a package substrate includes a core layer including a polymer-derived ceramic. The polymer-derived ceramic may include filler particles to control shrinkage and reduce warpage of the core layer during fabrication and use of the package substrate. The core layer may include counterbores or blind holes to embed a contact pad or an electrical interconnect in the core layer. A semiconductor die may be mounted on the package substrate and may be electrically connected to the contact pad or the electrical interconnect.
