Abstract:
Series switches for power delivery. A regulator operated as a current source is arranged in parallel with a switched capacitor divider. A switched capacitor divider is configured in series with a plurality of linear regulators with each regulating one of a plurality of voltage outputs from the switched capacitor divider. In another embodiment, a series switch bridge has a first pair of switches connected in series with a second pair of switches across a voltage input, each switch within a pair of switches is switched in-phase with the other while the first pair of switches is switched out of phase with the second pair of switches. A balancing capacitor is coupled across one switch in both the first and second pair to be in parallel when either of the pair of switches is closed to reduce a charge imbalance between the switches.
Abstract:
A method of forming a waveguide comprises forming an elongate waveguide core including a dielectric material; and arranging a conductive sheet around an outside surface of the dielectric core to produce a conductive layer around the waveguide core.
Abstract:
An antenna device includes an antenna on a substrate, a low-impedance electrostatic discharge (ESD) path for an ESD pulse from the antenna to a ground terminal, and a signal path between the antenna and either a signal terminal or an integrated circuit (IC) die. The ESD and signal paths may each include separate vias through the substrate. A capacitor may couple a signal to or from the antenna and the signal terminal (or IC die) but block low-frequency power (such as an ESD pulse). The ESD path has an electrical length of a quarter of the wavelength and so may present a high impedance to ground for the signal. The antenna device may include or be coupled to an IC die. The IC die may couple to the signal and ground terminals, e.g., opposite the substrate from the antenna.
Abstract:
Described herein are integrated circuit devices that include semiconductor devices near the center of the device, rather than towards the top or bottom of the device. In this arrangement, heat can become trapped inside the device. Metal fill, such as copper, is formed within a portion of the device, e.g., over the semiconductor devices and any front side interconnect structures, to transfer heat away from the semiconductor devices and towards a heat spreader.
Abstract:
Described herein are integrated circuit devices that include semiconductor devices near the center of the device, rather than towards the top or bottom of the device, and integrated inductors formed over the semiconductor devices. Power delivery to the device is on the opposite side of the semiconductor devices. The integrated inductors may be used for power step-down to reduce device thickness and/or a number of power rails.

Abstract:
In various embodiments, disclosed herein are systems and methods directed to the fabrication of a coreless semiconductor package (e.g., a millimeter (mm)-wave antenna package) having an asymmetric build-up layer count that can be fabricated on both sides of a temporary substrate (e.g., a core). The asymmetric build-up layer count can reduce the overall layer count in the fabrication of the semiconductor package and can therefore contribute to fabrication cost reduction. In further embodiments, the semiconductor package (e.g., a millimeter (mm)-wave antenna packages) can further comprise dummification elements disposed near one or more antenna layers. Further, the dummification elements disposed near one or more antenna layers can reduce image current and thereby increasing the antenna gain and efficiency.
Abstract:
Thermally conductive, electrically insulating materials and their manufacture on integrated circuit (IC) dies. An IC die may include a substrate with transistors on one side and, on the first and/or a second side, electrically insulating materials enhanced with thermally conductive materials. Such an IC die may be included in a system with a power supply. Such materials may be co-deposited, or interspersed, or interleaved together in a composite material.
