Abstract :
Reliable operation of MEMS requires development of accelerated testing techniques and protocols. One such technique using resonant fatigue specimens has demonstrated a failure mode that was previously unknown. This work indicates that moisture can decrease the lifetime of cyclicly stressed polysilicon components
