  • Patent number: 11894329
    Abstract: Sacrificial pillars for a semiconductor device assembly, and associated methods and systems are disclosed. In one embodiment, a region of a semiconductor die may be identified to include sacrificial pillars that are not connected to bond pads of the semiconductor die, in addition to live conductive pillars connected to the bond pads. The region with the sacrificial pillars, when disposed in proximity to the live conductive pillars, may prevent an areal density of the live conductive pillars from experiencing an abrupt change that may result in intolerable variations in heights of the live conductive pillars. As such, the sacrificial pillars may improve a coplanarity of the live conductive pillars by reducing variations in the heights of the live conductive pillars. Thereafter, the sacrificial pillars may be removed from the semiconductor die.

  • Patent number: 11871463
    Abstract: A method and device for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. The method stores, in a memory in at least one of the IMD or the EI, a base scanning schedule that defines a pattern for scanning windows over a scanning state. The method enters the scanning state during which a receiver scans for advertisement notices during the scanning windows. At least a portion of the scanning windows are grouped in a first segment of the scanning state. The method stores, in the memory, a scan reset pattern for restarting the scanning state. Further, the method automatically restarts the scanning state based on the scan reset pattern to form a pseudo-scanning schedule that differs from the base scanning schedule and establishes a communication session between the IMD and the EI.
