Abstract:
Some features pertain to a device package that includes a die and a package substrate. The die includes a first switch. The package substrate is coupled to the die. The package substrate includes at least one dielectric layer, a primary inductor, and a first secondary inductor coupled to the first switch of the die. The first secondary inductor and the first switch are coupled to a plurality of interconnects configured to provide an electrical path for a reference ground signal. The primary inductor is configurable to have different inductances by opening and closing the first switch coupled to the first secondary inductor. In some implementations, the primary inductor is configurable in real time while the die is operational. In some implementations, the die further includes a second switch, and the package substrate further includes a second secondary inductor coupled to the second switch of the die.
Abstract:
Many aspects of an improved IC package are disclosed herein. The improved IC package exhibits low-impedance and high power and signal integrity. The improved IC package comprises an IC die mounted on a multilayer coreless substrate. The thicknesses of prepreg layers of the coreless substrate are specific chosen to minimize warpage and to provide good mechanical performance. Each of the prepreg layers may have different coefficient of thermal expansion (CTE) and/or thickness to enable better control of the coreless substrate mechanical properties. The improved IC package also includes a vertically mounted die side capacitor and a conductive layer formed on the solder resist layer of the substrate. The conductive layer is formed such that it also encapsulates the vertically mounted capacitor while being electrically coupled to one of the capacitor's electrode.

Some novel features pertain to an integrated device package that includes a die, an electromagnetic (EM) passive device, an encapsulation layer covering the die and the EM passive device, and a redistribution portion coupling the die and the EM passive device. In some implementations, the EM passive device includes an electromagnetic (EM) passive device. The EM passive device includes a base layer, a via traversing the base layer, a pad coupled to the via, and at least redistribution layer configured to operate as electromagnetic (EM) passive component, where the redistribution layer is coupled to the pad. The redistribution portion of the EM passive device includes at least one redistribution layer that is configured to electrically couple the die to the EM passive device. The redistribution portion includes at least one redistribution layer that is configured as an electromagnetic (EM) shield.

Some novel features pertain to an integrated device that includes a substrate, a first interconnect coupled to the substrate, and a second interconnect surrounding the first interconnect. The second interconnect may be configured to provide an electrical connection to ground. In some implementations, the second interconnect includes a plate. In some implementations, the integrated device also includes a dielectric material between the first interconnect and the second interconnect. In some implementations, the integrated device also includes a mold surrounding the second interconnect. In some implementations, the first interconnect is configured to conduct a power signal in a first direction. In some implementations, the second interconnect is configured to conduct a grounding signal in a second direction. In some implementations, the second direction is different from the first direction. In some implementations, the integrated device may be a package-on-package (PoP) device.
Abstract:
A package on package (PoP) device includes a first package and a second package. The first package includes a first package substrate, a die coupled to the first package substrate, an encapsulation layer located on the first package substrate, and an inter package connection coupled to the first package substrate. The inter package connection is located in the encapsulation layer. The inter package connection includes a first interconnect configured to provide a first electrical path for a reference ground signal, and a second set of interconnects configured to provide at least one second electrical path for at least one second signal. The first interconnect has a length that is at least about twice as long as a width of the first interconnect. The second set of interconnects is configured to at least be partially coupled to the first interconnect by an electric field.

Some novel features pertain to a semiconductor device that includes a substrate, a first cavity that traverses the substrate. The first cavity is configured to be occupied by a interconnect material (e.g., solder ball). The substrate also includes a first metal layer coupled to a first side wall of the first cavity. The substrate further includes a first integrated passive device (IPD) on a first surface of the substrate, the first IPD coupled to the first metal layer. In some implementations, the substrate is a glass substrate. In some implementations, the first IPD is one of at least a capacitor, an inductor and/or a resistor. In some implementations, the semiconductor device further includes a second integrated passive device (IPD) on a second surface of the substrate. The second IPD is coupled to the first metal layer.
