Manufacturing variation in the micro fabrication process inevitably alters the size of the designed structure and thereafter influences the performance of devices to some extent. A good knowledge of this effect will help the design and optimization of the devices. In this letter, we propose an analytical model to investigate the effect of manufacturing variation on the individual resonator in a chain of coupled micro mechanical resonators. The model is also used in a reverse manner to estimate the possible range of manufacturing variation based on the designed value and the measured frequency response.
