Abstract:
A resistor structure composed of a metal liner is embedded within a MOL dielectric material and is located, at least in part, on a surface of a doped semiconductor material structure. The resistor structure is located on a same interconnect level of the semiconductor structure as a lower contact structure and both structures are embedded within the same MOL dielectric material. The metal liner that provides the resistor structure is composed of a metal or metal alloy having a higher resistivity than a metal or metal alloy that provides the contact metal of the lower contact structure.
