Abstract:

Some advantages of predicting reliability include providing advance warning signs of failure, and the reduction of life cycle costs by reducing inspection and unscheduled maintenance. However, predictions can be inaccurate if they do not account for the actual environments that the product is subjected to in its life cycle. This paper describes an in-situ sensor (prognostic monitor) approach, which can be used to estimate the accumulated damage and the remaining life of semiconductor devices.
