  • Publication number: 20080145958
    Abstract: A monitor semiconductor chip that incorporates ESD sensitive resistors is subjected to the same steps in a semiconductor manufacturing process to which functional semiconductor chips are subjected. The ESD sensitive resistors are configured to experience non-volatile changes in resistance in response to ESD events, such that the resistors retain the changes in resistance after dissipation of the ESD events have occurred. As a result, the occurrence of an ESD event, and in some instances, the magnitude of an ESD event, can be detected by monitoring the resistance of the ESD sensitive resistors after one or more steps in a semiconductor manufacturing process.
