  • Die connection monitoring system and method
    Patent number: 8829918
    Abstract: A system for monitoring a die connection includes a die bonded to a substrate and a connection indicator circuit coupled to a monitor pad of the die. The connection indicator circuit is configured to detect a connection failure of the monitor pad. A signal corresponding to the monitor pad of the die is monitored, and an indication of a pad connection failure associated with the monitor pad is provided in response to a change in the monitored signal.
    Type: Grant
