A test structure for an integrated circuit device includes a series inductor, capacitor, resistor (LCR) circuit having one or more inductor elements, with each inductor element having at least one unit comprising a first segment formed in a first metal layer, a second segment connecting the first metal layer to a semiconductor substrate beneath the first metal layer, and a third segment formed in the semiconductor substrate; and a capacitor element connected in series with each inductor element, the capacitor element defined by a transistor gate structure including a gate electrode as a first electrode, a gate dielectric layer, and the semiconductor substrate as a second electrode.
