Abstract:
A method is for manufacturing a microeletromechanical system resonator having a semiconductor device and a microelectromechanical system structure unit formed on a substrate. The method includes: forming a lower electrode of an oxide-nitride-oxide capacitor unit included in the semiconductor device using a first silicon layer; forming, using a second silicon layer, a substructure of the microelectromechanical system structure unit and an upper electrode of the oxide-nitride-oxide capacitor unit included in the semiconductor device; and forming, using a third silicon layer, a superstructure of the microelectromechanical system structure unit and a gate electrode of a complementary metal oxide semiconductor circuit unit included in the semiconductor device.
