Abstract:
The present application provides planar and stacked resistor structures that are embedded within an interconnect dielectric material in which the resistivity of an electrical conducting resistive material or electrical conducting resistive materials of the resistor structure can be tuned to a desired resistivity during the manufacturing of the resistor structure. Notably, a doped metallic insulator layer is formed atop a substrate. A controlled surface treatment process is then performed to an upper portion of the doped metallic insulator layer to convert the upper portion of the doped metallic insulator layer into an electrical conducting resistive material layer. The remaining doped metallic insulator layer and the electrical conducting resistive material layer are then patterned to provide the resistor structure.
