发明名称 METAL-INSULATOR-METAL CAPACITORS
摘要 Metal-insulator-metal capacitors are provided that are formed in integrated circuit dielectric stacks. A line-plate-line capacitor is provided that alternates layers that contain metal plates with layers that contain straight or angled parallel lines of alternating polarity. A segmented-plate capacitor is provided that has metal plates that alternate in polarity both within a layer and between layers. The line-plate-line and segmented-plate capacitors may exhibit a reduced parasitic inductive coupling. The capacitances of the line-plate-line capacitor and the metal-insulator-metal capacitor may have an enhanced contribution from an interlayer capacitance component with a vertical electric field than a horizontal intralayer capacitance component with a horizontal electric field.
