ABSTRACT:
A semiconductor device includes a first capacitor comprising a plurality of first unit capacitors interconnected to each other, each having a first unit capacitance; and a second capacitor comprising a plurality of second unit capacitors interconnected to each other, each having a second unit capacitance, wherein the first unit capacitors and the second unit capacitors have equal numbers of unit capacitors. The first unit capacitors and the second unit capacitors are arranged in an array with rows and columns and placed in an alternating pattern in each row and each column. The first and the second unit capacitors each have a total number greater than two.
