Outgassing of materials used for thin film vacuum packages

In this paper, outgassing of the thin film vacuum package is analyzed by integrated MEMS (Microelectromechanical system) resonator and RBS (Rutherford backscattering spectroscopy). Outgassing behavior of different thin film packaging materials is studied by exodiffusion experiments. It is demonstrated that a high temperature pre anneal will greatly reduce the outgassing but can not eliminate it.
