VERTICAL MEANDER INDUCTOR FOR SMALL CORE VOLTAGE REGULATORS

摘要

Vertical meander inductors for small core voltage regulators and approaches to fabricating vertical meander inductors for small core voltage regulators are described. For example, a semiconductor die includes a substrate. An integrated circuit is disposed on an active surface of the substrate. An inductor is coupled to the integrated circuit. The inductor is disposed conformal with an insulating layer disposed on an essentially planar surface of the substrate. The insulating layer has an undulating topography.
