摘要:
A device may include a first conductive element and an interlevel dielectric arranged over the first conductive element. The device may further include a dual damascene opening including a first end, a second end, and sidewalls extending between the first and second ends, the sidewalls extending through the interlevel dielectric. A metal-insulator-metal (MIM) stack may line the dual damascene opening. The MIM stack may include a first conductive liner lining the sidewalls and the second end of the dual damascene opening, an insulator layer lining the first conductive liner, and a second conductive liner lining the insulator layer. A first metal interconnect may be disposed in and filling the dual damascene opening lined with the MIM stack.
