METAL-INSULATOR-METAL BACK END OF LINE CAPACITOR STRUCTURES
Abstract:
Embodiments of the present invention provide improved metal-insulator-metal (MIM) capacitors. In embodiments, series resistance is reduced by forming a via underneath the bottom plate of a MIM capacitor, leading to a metallization layer or intermediate metal sublayer. In embodiments, the MIM capacitor is formed with a corrugated shape to increase the plate surface area, allowing a thicker dielectric to be used, thereby mitigating leakage issues.
