Abstract: Middle-of-line (MOL) metal resistor temperature sensors for localized temperature sensing of active semiconductor areas in integrated circuits (ICs) are disclosed. One or more metal resistors are fabricated in a MOL layer in the IC adjacent to an active semiconductor area to sense ambient temperature in the adjacent active semiconductor area. Voltage of the metal resistor will change as a function of ambient temperature of the metal resistor, which can be sensed to measure the ambient temperature around devices in the active semiconductor layer adjacent to the metal resistor. By fabricating a metal resistor in the MOL layer, the metal resistor can be localized adjacent and close to semiconductor devices to more accurately sense ambient temperature of the semiconductor devices. The same fabrication processes used to create contacts in the MOL layer can be used to fabricate the metal resistor.

Abstract: 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).
