Abstract
An integrated passive device (IPD) structure includes an electronic component having an active surface and an opposite inactive surface. The IPD structure further includes a passive device structure extending through the electronic component between the active surface and the inactive surface and having a portion(s) formed on the active surface, the inactive surface, or both the active and inactive surfaces. Accordingly, the IPD structure includes the functionality of the electronic component, e.g., an integrated circuit chip, and of the passive device structure, e.g., one or more capacitors, resistors, inductors, or surface mounted components. By integrating the passive device structure with the electronic component to form the IPD structure, separate mounting of passive component(s) to the substrate is avoided this minimizing the substrate size.
