This paper discusses the optimization of series resistance of nonplanar metal-insulator-metal capacitor, i.e., an original 3-D capacitor with a capacitance density of 35 nF/mm², used in very large scale integration. A fully analytical and physically based model of its series resistance versus material and geometrical parameters has been developed, in excellent agreement with both 3-D numerical simulations and experiments. Based on the modeling results, possible design strategies of series-resistance reduction are suggested; showing a reduction of the series resistance by approximately a factor of four, without any degradation of the capacitance density.
