Abstract:
Methods for forming structures to use in atomic force probing of a conductive feature embedded in a dielectric layer and structures for use in atomic force probing. An insulator layer is formed on the dielectric layer such that the conductive feature is covered. A contact hole penetrates from a top surface of the insulator layer through the insulator layer to the conductive feature. The contact hole is at least partially filled with a conductive stud that is in electrical contact with the conductive feature and exposed at the top surface of the insulator layer so as to define a structure. A probe tip of an atomic force probe tool is landed on a portion of the structure and used to electrically characterize a device structure connected with the conductive feature.
