Abstract: Embodiments of the invention include an electrical package and methods of forming the package. In one embodiment, the electrical package may include a first package layer. A plurality of signal lines with a first thickness may be formed on the first package layer. Additionally, a power plane with a second thickness may be formed on the first package layer. According to an embodiment, the second thickness is greater than the first thickness. Embodiments of the invention may form the power plane with a lithographic patterning and deposition process that is different than the lithographic patterning and deposition process used to form the plurality of signal lines. In an embodiment, the power plane may be formed concurrently with vias that electrically couple the signal lines to the next routing layer.

Abstract: A vertically ground isolated package device can include (1) ground shielding attachment structures and shadow voiding for data signal contacts; (2) vertical ground shielding structures and shield fencing of vertical data signal interconnects; and (3) ground shielding for an electro-optical module connector of the package device. These reduce cross talk between data signal contacts, attachment structures and vertical “signal” interconnects of the package device. The ground shielding attachment structures may include patterns of solder bumps and/or surface contacts. The shadow voiding may be surrounding voids in ground planes that are larger than the data signal solder bumps. The vertical ground shielding structures may include patterns of ground shield interconnects between the vertical data signal interconnects: The shield fencing may include patterns of ground plated through holes (PTH) and micro-vias (uVia).

Abstract: Disclosed is a signaling system. The signaling system may comprise a transmitter, a receiver, and a package interconnect. The transmitter may be configured to transmit M signals. The receiver may be configured to receive the M signals. The package interconnect may include a bundle of N wires electrically connecting the transmitter and the receiver. During operation, the N wires may be electromagnetically coupled with each other and the M signals may travel between the transmitter and the receiver on the bundle of N wires.

Abstract: Embodiments of the invention include package substrates that include microchannels and methods of making such package substrates. In an embodiment, the package substrate may include a first package layer. In some embodiments, a bottom channel wall may be formed over the first package layer. Embodiments may also include a channel sidewall that is formed in contact with the bottom channel wall. An organic dielectric layer may be formed over the first package layer. However, embodiments include a package substrate where the dielectric layer is not present within a perimeter of the channel sidewall. Additionally, a top channel wall may be supported by the channel sidewall. According to an embodiment, the top channel wall, the channel sidewall, and the bottom channel wall define a microchannel.

Abstract: In accordance with one aspect of the present description, a transmission line such as a microstrip or stripline transmission line, has stub-shaped projections adapted to compensate simultaneously for both far-end crosstalk (FEXT) induced by inductive coupling between the transmission line and an adjacent transmission line, and also far-end crosstalk induced by inductive coupling between the vertical electrical interconnect at the far end of the transmission line and an adjacent vertical electrical interconnect electrically connected to the adjacent transmission line. In another aspect of the present description, a microstrip transmission line may have multiple stubby line sections having different resistances and impedances to more gradually transition from to the typically low impedance characteristics of vertical interconnects such as the PTH vias and socket connectors. Other aspects are described.
