Abstract :
Several classes of microelectromechanical systems (MEMS) are sensitive to the internal pressure inside their packages. From functionality and reliability point of view, knowing and monitoring this pressure is important. This paper demonstrates for the first time a new method to measure the internal pressure of the package and, in addition, its leakage rate. It is based on an innovative use of the Focused Ion Beam (FIB) together with a measurement of pressure sensitive parameters.
