Inductor fabricated with dry film resist and cavity and method of fabricating the inductor
An inductor fabricated with a dry film resist and a cavity and a method of fabricating the inductor. The cavity can be formed in a substrate to minimize a parasitic capacitance generated by structures of upper electrodes, an insulating layer, and a lower electrode and minimize energy loss caused by an eddy current generated through the substrate. Also, a process of forming and planarizing the cavity can be simplified so as to form the cavity to a sufficient depth. As a result, an inductor having a high quality factor and a high self resonant frequency can be fabricated. Also, a scheme for simply forming and planarizing a cavity is contemplated.
