A comb-tooth-shaped capacitor is a common structural type of a micro-actuator and a micro-sensor of MEMS devices. Gaps between teeth of the comb-tooth-shaped capacitor are only several micrometers, and a gap between a positive plate and a negative plate needs to be fine controlled. The invention provides a comb-tooth capacitor accurate assembly method based on a bi-stable state compliant mechanism. The comb-tooth capacitor accurate assembly method based on the bi-stable state compliant mechanism can improve fine control of the gap between the positive plate and the negative plate of the comb-tooth-shaped capacitor, so that a batch of MEMS devices with the same structure have the same and estimable capacitance, and uniformity of performance of the static MEMS devices at the time of lot manufacturing is improved.
