Abstract

A plurality of diode/resistor devices are formed within an integrated circuit structure using manufacturing equipment operatively connected to a computerized machine. Each of the diode/resistor devices comprises a diode device and a resistor device integrated into a single structure. The resistance of each of the diode/resistor devices is measured during testing of the integrated circuit structure using testing equipment operatively connected to the computerized machine. The current through each of the diode/resistor devices is also measured during testing of the integrated circuit structure using the testing equipment. Then, response curves for the resistance and the current are computed as a function of variations of characteristics of transistor devices within the integrated circuit structure and/or variations of manufacturing processes of the transistor devices within the integrated circuit structure.
