INDUCTOR EMBEDDED IN A PACKAGE SUBTRATE

摘要

Some novel features pertain to a package substrate that includes a core layer, a first via, a first dielectric layer, and a first inductor. The core layer includes a first surface and a second surface. The first via is located in the core layer. The first dielectric layer is coupled to the first surface of the core layer. The first inductor is located in the first dielectric layer. The first inductor is coupled to the first via in the core layer. The first inductor is configured to generate a magnetic field that laterally traverses the package substrate. In some implementations, the package substrate further includes a first pad coupled to the first inductor, wherein the first pad is configured to couple to a solder ball. In some implementations, the package substrate includes a second via located in the core layer, and a second inductor located in the first dielectric layer.
