ABSTRACT:
A manufacturing method for the inductor/transformer is disclosed. A simulator is used to simulate the inductance, the quality factor, and the self-resonance frequency of said inductor/transformer to generate at least one group of the area size, the number of the conductive layer, the line width, the number of turns, and/or the line space of the conductive layers and the first conductive layer; the inductor/transformer is manufactured according to the factors. Thereafter, the Monte-Carlo simulation is used to initiate the process variability analysis of the factors of the conductive layer and the first conductive layer, and the geometric size of the inductor/transformer can be modulated according to the results of the process variability analysis during the manufacturing process, such that the inductor/transformer can be manufactured by the process of the generic logic circuit.
