VERTICAL INDUCTOR FOR WLCSP

摘要

Embodiments of the invention include a microelectronic device and methods of forming a microelectronic device. In an embodiment the microelectronic device includes a semiconductor die and an inductor that is electrically coupled to the semiconductor die. The inductor may include one or more conductive coils that extend away from a surface of the semiconductor die. In an embodiment each conductive coils may include a plurality of traces. For example, a first trace and a third trace may be formed over a first dielectric layer and a second trace may be formed over a second dielectric layer and over a core. A first via through the second dielectric layer may couple the first trace to the second trace, and a second via through the second dielectric layer may couple the second trace to the third trace.
