Abstract
A circuit structure with a capacitor or a resistor includes a semiconductor substrate, a first conductive region positioned in the semiconductor substrate, a plurality of second conductive regions and third conductive regions positioned in the first conductive region, a first depletion region positioned between the first conductive region and the third conductive region, a second depletion region positioned between the second conductive region and the third conductive region, and a plurality of separating regions positioned in the first conductive region, configured to separate the second and the third conductive regions. In operation, a first voltage is applied to the separating region to control the capacitance or the resistance of the circuit structure. A second voltage is applied to the first conductive region and a third voltage is applied to the second conductive region to measure the capacitance and the resistance of the circuit structure.
