Abstract: The invention relates to a field of semiconductor manufacturing technology, more particularly, to a method for preparing three-dimensional integrated inductor-capacitor structure, which can realize the inductor-capacitor of three-dimensional structure, and form three-dimensional spiral inductor centering on the magnetic cores of single direction around through the preparation of the interconnected top metal conducting wires and bottom metal conducting wires, which can gain capacitance and inductance at the same time in a relatively small space, and reduce the production costs, and also greatly improves the inductance magnetic flux in order to increase the inductance value and reduce eddy current, and improve the quality factor Q value and the performance of inductance coil.
