Estimate the capacitance to ground per unit length for a copper interconnect 0.7 m in height and with widths of 0.20 m, 0.4 m, 1.2 m, 2.5 m and 5.0 m. The dielectric is silicon dioxide, 0.35 m thick. For each case, calculate the unit-length parallel-plate capacitance value and comment on whether fringing field capacitance is dominant or parallel plate capacitance
