A new system for the in situ extraction of the material parameters of MEMS films is presented. The system is composed of three parts,including the layout of testing structures,test equipments,and a software application for analysis and control.Both the test and measurement signals of the test system are electrical,making it compatible with IC testing and capable for rapid testing.The measurement is executed automatically under the control of a computer.
