Abstract:
A semiconductor package (100) may be formed by an embedded package (110) stacked on dies. The embedded package may comprise a first substrate (106) with one or more dies (302,304) attached to one side (132) of the first substrate (106). One or more dies (102,104) may be stacked on the opposite side (134) of the first substrate. The embedded package may be stacked on a die (202,204) mounted on a second substrate (206) with the first substrate coupled to the second substrate at the other side. The entire assembly may be encapsulated.
Abstract:
Described herein are magnetic core inductors (MCI) and methods for manufacturing magnetic core inductors. A first embodiment of the MCI can be a snake-configuration MCI. The snake-configuration MCI can be formed by creating an opening in a base material, such as copper, and providing a nonconductive magnetic material in the opening. The inductor can be further formed by forming plated through holes into the core material. The conductive elements for the inductor can be formed in the plated through holes. The nonconductive magnetic material surrounds each conductive element and plated through hole. In embodiments, a layered coil inductor can be formed by drilling a laminate to form a cavity through the laminate within the metal rings of the layered coil inductor. The nonconductive magnetic material can be provided in the cavity.
Abstract:
Disclosed herein are magnetic structures in integrated circuit (1C) package supports, as well as related methods and devices. For example, in some embodiments, an 1C package support may include a conductive line and a magnetic structure around a top surface of the conductive line and side surfaces of the conductive line. The magnetic structure may have a tapered shape that narrows toward the conductive line.
Abstract:
Methods/structures of forming in-package inductor structures are described. Embodiments include a substrate including a dielectric material, the substrate having a first side and a second side. A conductive trace is located within the dielectric material. A first layer is on a first side of the conductive trace, wherein the first layer comprises an electroplated magnetic material, and wherein a sidewall of the first layer is adjacent the dielectric material. A second layer is on a second side of the conductive trace, wherein the second layer comprises the electroplated magnetic material, and wherein a sidewall of the second layer is adjacent the dielectric material.
