The stress relief region includes a conductive structure electrically coupling circuitries of the stress domains between which the conductive structure is disposed.
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 hybrid package having a processor module disposed on a substrate and an auxiliary module disposed on a patterned lid. The auxiliary module may be a memory module, a power management integrated circuit (PMIC) module, and/or other suitable module, that are located in the package along with the processor module. Having the auxiliary module in the package with the processor module reduces the noise at the solder bump between the processor module and the substrate. Having the auxiliary module in the package with the processor module also allows other modules to be added to the package without increasing the area of the package.

The method forms a plurality of conductive traces external to the substrate and couples the plurality of conductive traces to the first plurality of vias: wherein the plurality of conductive traces and the first plurality of vias comprise a plurality of conductive turns and wherein the plurality of conductive turns are in a spiral configuration substantially within a first plane.
Abstract:
Silicon-on-insulator (SOI) wafers employing molded substrates to improve insulation and reduce current leakage are provided. In one aspect, a SOI wafer comprises a substrate. An insulating layer (e.g., a buried oxide (BOX) layer) is disposed above the substrate to insulate an active semiconductor layer disposed above the insulating layer, from the substrate. Transistors are formed in the active semiconductor layer. To provide for improved insulation between the active semiconductor layer and the substrate to reduce leakage and improve performance of the active semiconductor layer, the substrate is provided in the form of a molded substrate. A coating layer is also disposed between the molded substrate and the insulating layer of the SOI wafer, in case, for example, the melting temperature of a molding compound used to form the molded substrate is not low enough to prevent contamination of the active semiconductor layer into the insulating layer.
Abstract:
An apparatus includes a substrate package and a three dimensional (3D) antenna structure formed in the substrate package. The 3D antenna structure includes multiple substructures to enable the 3D antenna structure to operate as a beam-forming antenna. Each of the multiple substructures has a slanted-plate configuration or a slanted-loop configuration.
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 package substrate includes at least one dielectric layer, a first stack of first interconnects in the at least one dielectric layer, and a second interconnect formed on at least one side portion of the at least one dielectric layer. The first stack of first interconnects is configured to provide a first electrical path for a non-ground reference signal, where the first stack of first interconnects is located along at least one side of the package substrate. The second interconnect is configured to provide a second electrical path for a ground reference signal.
