摘要:
A bottom package substrate is provided that includes a plurality of metal posts that electrically couple through a die-side redistribution layer to a plurality of die interconnects. The metal posts and the die interconnects are plated onto a seed layer on the bottom package substrate.

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.

A substrate includes a plurality of vias (210) that are lined with dielectric polymer (215) having a substantially uniform thickness. This substantial uniform thickness provides a lumen within each dielectric-polymer-layer-lined via that is substantially centered within the via. Subsequent deposition of metal (220) into the lumen for each dielectric-polymer-layer-lined via thus provides conductive vias having substantially centered metal conductors.

One feature pertains to a multi-chip package that includes a substrate and an electromagnetic interference (EMI) shield coupled to the substrate. At least one integrated circuit is coupled to a first surface of the substrate. The EMI shield includes a metal casing configured to shield the package from radio frequency radiation, a dielectric layer coupled to at least a portion of an inner surface of the metal casing, and a plurality of signal lines. The signal lines are coupled to the dielectric layer and electrically isolated from the metal casing by the dielectric layer. At least one other integrated circuit is coupled to an inner surface of the EMI shield, and at least a portion of the inner surface of the EMI shield faces the first surface of the substrate. The signal lines are configured to provide electrical signals to the second circuit component.

A package-on-package (POP) structure is disclosed. The POP structure includes a first die, a second die, and a photo-imaged dielectric (PID) layer. The PID layer is disposed between the first die and the second die. The POP structure also includes a first conductive path from the first die through the PID layer to the second die. The first conductive path extends directly through a first area of the PID layer directly between the first die and the second die. The POP structure further includes a second conductive path from the first die through the PID layer to the second die. A particular portion of the second conductive path is perpendicular to the first conductive path and extends through a second area of the PID layer not directly between the first die and the second die.

A semiconductor package according to some examples of the disclosure may include a base (110) with a first redistribution layer (150) on one side, first (120) and second (130) side-by-side die attached to the base on an opposite side from the first redistribution layer, an interposer (140) attached to active sides of the first and second die to provide an interconnection between the first and second die, a plurality of die vias (180,181) extending from the first and second die to a second redistribution layer (170) on a surface of the package opposite the first redistribution layer, and a plurality of package vias (182) extending through the package between the first and second redistribution layers.
