Abstract:
Some novel features pertain to a capacitor structure that includes a first conductive layer, a second conductive layer and a non-conductive layer. The first conductive layer has a first overlapping portion and a second overlapping portion. The second conductive layer has a third overlapping portion, a fourth overlapping portion, and a non-overlapping portion. The third overlapping portion overlaps with the first overlapping portion of the first conductive layer. The fourth overlapping portion overlaps with the second overlapping portion of the first conductive layer. The non-overlapping portion is free of any overlap (e.g., vertical overlap) with the first conductive layer. The non-conductive layer separates the first and second conductive layers. The non-conductive layer electrically insulates the third overlapping portion and the fourth overlapping portion from the first conductive layer.
Abstract:
A fan-out wafer level package structure may include a multilayer redistribution layer (RDL). The multilayer RDL may be configured to couple with terminals of an embedded capacitor. The multilayer RDL may include sections with fewer layers than other sections of the multilayer RDL according to a selected equivalent series resistance (ESR) control pattern.
Abstract:
A substrate that includes a first dielectric layer and a capacitor embedded in the first dielectric layer. The capacitor includes a base portion, a first terminal and a second terminal. The first terminal is located on a first surface of the base portion, where the first terminal is the only terminal on the first surface of the base portion. The second terminal is located on a second surface of the base portion. The second surface is opposite to the first surface. The second terminal is the only terminal on the second surface of the base portion. In some implementations, the capacitor further includes a first base metal layer located between the first surface of the base portion and the first terminal. In some implementations, the capacitor also includes a second base metal layer located between the second surface of the base portion and the second terminal.

The first metal layer is coupled to the first and third terminals. The first metal layer, the first terminal, and the third terminal are configured to provide a first electrical path for a first signal. The second metal layer is coupled to the second terminal. The second metal layer and the second terminal are configured to provide a second electrical path for a second signal.
Abstract:
A package substrate that includes a first portion and a redistribution portion. The first portion is configured to operate as a capacitor. The first portion includes a first dielectric layer, a first set of metal layers in the dielectric layer, a first via in the dielectric layer, a second set of metal layers in the dielectric layer, and a second via in the dielectric layer. The first via is coupled to the first set of metal layers. The first via and the first set of metal layers are configured to provide a first electrical path for a ground signal. The second via is coupled to the second set of metal layers. The second via and the second set of metal layers are configured to provide a second electrical path for a power signal. The redistribution portion includes a second dielectric layer, and a set of interconnects.
Abstract:
A planar capacitor includes, in part, a first metal line forming spiral-shaped loops around one of its end point, and a second metal line forming spiral-shaped loops between the loops of the first metal line. The first and second metal lines are coplanar, formed on an insulating layer, and form the first and second plates of the planar capacitor. The planar capacitor may be used to form a filter. Such a filter includes a first metal line forming first spiral-shaped loops, a second metal line forming second spiral-shaped loops, and a third metal line—coplanar with the first and second metal lines—forming loops between the loops of the first and second metal lines. The filter further includes a first inductor coupled between the first and third metal lines, and a second inductor coupled between the second and third metal lines.
