| dc.description.abstract | This paper derives an approximate analytical solution to the pull-in voltage of micro bridge with non-ideal boundaries, fringing field capacitance and residual stresses. Besides, this paper also presents a novel and high-precision algorithm and method for extracting the Young’s modulus and residual stress of thin films through the pull-in voltage of micro test-key at wafer level. The approximate analytical solution is derived based on the Euler’s beam model and the minimum energy method. We derive a closed form solution for the pull-in voltages of micro fixed-fixed beam subjected to electrostatic loads and initial stress. Then one can use the aforesaid closed form solution of the pull-in voltage to extract the Young’s modulus and residual stress of the test structures. The test cases include single crystal silicone, poly-silicon, and sputtered aluminum. The accuracy of the present approximate analytical solution is verified through comparing with simulation results of commercial packages as well as experimental measured ones. The deviation of the present approximate analytical solution is within 5% for wide beam and narrow beam in small deflection regime. The deviation of the extracted Young’s modulus and residual stress are both within 5%. The present solution is fully analytical and highly accurate for device design. It can give us explicit physical meaning about how the residual stress, elastic boundary, structural flexibility, fringing field capacitance to affect pull-in voltage. The present method is expected to be applicable to the wafer-level testing in micro-device manufacture and compatible with the wafer-level testing in IC industry since the test and pick-up signals are both electrical. | en |
