Abstract:
A multiplexer structure (500) includes a passive substrate (508). The multiplexer structure (500) may also include a high band filter (502) on the passive substrate. The high band filter (502) may include a 2D planar spiral inductor(s) (530, 540) on the passive substrate. The multiplexer structure (500) may further include a low band filter (504) on the passive substrate. The low band filter (504) may include a 3D through-substrate inductor (510, 520) and a first capacitor(s) on the passive substrate. The multiplexer structure (500) may also include a through substrate via(s) (VIA) coupling the high band filter (502) and the low band filter (504).
Abstract:
An exemplary MIM capacitor may include a first metal plate, a dielectric layer on the first metal plate, a second metal plate on the dielectric layer, a via layer on the second metal plate, and a third metal plate on the via layer where the second metal plate has a tapered outline with a first side and a second side longer than the first side such that the second side provides a lower resistance path for a current flow.
Abstract:
Ground shielding is achieved by a conductor shield having conductive surfaces that immediately surround individual chips within a multichip module or device, such as a multichip module or device with flip-chip (FC) bumps. Intra-module shielding between individual chips within the multichip module or device is achieved by electromagnetic or radio-signal (RF) isolation provided by the surfaces of the conductor shield immediately surrounding each of the chips. The conductor shield is directly connected to one or more grounded conductor portions of a substrate or interposer to ensure reliable grounding.
Abstract:
A device includes a stress relief region between at least two stress domains of a substrate (e.g., of a semiconductor die or other integrated circuit). The stress relief region includes a conductive structure electrically coupling circuitries of the stress domains between which the conductive structure is disposed.
Abstract:
A low-profile passive-on-package is provided that includes a plurality of recesses that receive corresponding interconnects. Because of the receipt of the interconnects in the recesses, the passive-on-package has a height that is less than a sum of a thickness for the substrate and an interconnect height or diameter.
Abstract:
Provided are space-efficient capacitors that have a higher quality factor than conventional designs and improve coupling of electrical energy from a through-glass via (TGV) to a dielectric. For example, provided is a TGV having a non-rectangular cross-section, where one end of the TGV is coupled to a first metal plate. A dielectric material is formed on the first metal plate. A second metal plate is formed on the dielectric material in a manner that overlaps at least a portion of the first metal plate to form at least one overlapped region of the dielectric material. At least a part of the perimeter of the overlapped region is non-planar. The overlapped region can be formed in a shape of a closed ring, in a plurality of portions of a ring shape, in substantially a quarter of a ring shape, and/or in substantially a half of a ring shape.
Abstract:
A filter includes a glass substrate having through substrate vias. The filter also includes capacitors supported by the glass substrate. The capacitors may have a width and/or thickness less than a printing resolution. The filter also includes a 3D inductor within the substrate. The 3D inductor includes a first set of traces on a first surface of the glass substrate coupled to the through substrate vias. The 3D inductor also includes a second set of traces on a second surface of the glass substrate coupled to opposite ends of the through substrate vias. The second surface of the glass substrate is opposite the first surface of the glass substrate. The through substrate vias and traces operate as the 3D inductor. The first set of traces and the second set of traces may also have a width and/or thickness less than the printing resolution.

The interface layer has a second surface on the first surface of the glass substrate such that the passive component and the at least one contact pad are located between the first surface of the glass substrate and the interface layer.

The interface layer also includes at least one via formed in the interface layer configured to electrically connect the at least one contact pad with the at least one LGA pad.

A conductive bump assembly may include a passive substrate. The conductive bump assembly may also include a conductive bump pad supported by the passive substrate and surrounded by a first passivation layer opening. The conductive bump assembly may further include a second passivation layer opening on the passive substrate. The second passivation layer opening may be merged with the first passivation layer opening surrounding the conductive bump pad proximate an edge of the passive substrate. The conductive bump assembly may also include a conductive bump on the conductive bump pad.
