  • Patent number: 10950555
    Abstract: Semiconductor packages and a method of forming a semiconductor package are described. The semiconductor package has a foundation layer, a conductive layer formed in the foundation layer, and a magnetic layer formed between the conductive and the foundation layer. The conductive layer and the magnetic layer are coupled to form a low-profile inductor shield. The semiconductor package also has a dielectric layer formed between the magnetic and foundation layer. The foundation layer is mounted between a motherboard and a semiconductor die, where the foundation layer is attached to the motherboard with solder balls. Accordingly, the low-profile inductor shield may include a z-height that is less than a z-height of the solder balls. The low-profile inductor shield may have solder pads that are coupled to the conductive layer. The foundation layer may include at least one of voltage regulator and inductor, where the inductor is located above the low-profile inductor shield.

  • Patent number: 9705182
    Abstract: A patch-based proximity sensor having a capacitance and/or inductance that varies based on a proximity of an animate body, a sense circuit to sense the capacitance and/or inductance, and a control system to compare one or more sensed values to one or more thresholds, and to selectively enable/disable one or more antennas based on the comparison(s). The threshold may correspond to a desired/permitted minimum distance between an antenna and an animate body, and/or a desired/permitted maximum electromagnetic energy exposure to the animate body. A multi-layer module may include one or more patch-based proximity sensors and one or more patch-antennas. Multiple antennas may be individually controllable based on corresponding proximity measures.
