Summary: | A complementary back end of line (BEOL) capacitor (CBC) structure includes a metal oxide metal (MOM) capacitor structure. The MOM capacitor structure is coupled to a first upper interconnect layer of an interconnect stack of an integrated circuit (IC) device. The MOM capacitor structure includes a lower interconnect layer of the interconnect stack. The CBC structure also includes a second upper interconnect layer of the interconnect stack coupled to the MOM capacitor structure. The CBC structure also includes a metal insulator metal (MIM) capacitor layer between the first upper interconnect layer and the second upper interconnect layer. In addition, CBC structure also includes a MIM capacitor structure coupled to the MOM capacitor structure. The MIM capacitor structure includes a first capacitor plate having a portion of the first upper interconnect layer, and a second capacitor plate having a portion of the MIM capacitor layer(s). |
