Abstract
An evaluation pattern and an evaluation method of devices capable of measuring with precision the unit capacitance and specific precision of passive devices necessary in analog circuits on a single semiconductor substrate, unit capacitors in such a quantity to overcome the measuring error of measuring instruments, arranged in an array by nx pieces in the X direction (nx being a natural number) and ny pieces in the Y direction (ny being a natural number), are connected by wiring to be capable of measuring the sum of capacitances in each column at least in one of the array directions in the X and Y directions of the unit capacitors.
