Popis: A recently developed conductive atomic force microscopy (cAFM) technique, nanoscale impedance microscopy (NIM), is presented as a characterization strategy for nanoelectronic devices and circuits. NIM concurrently monitors the amplitude and phase response of the current through a cAFM tip in response to a temporally periodic applied bias. By varying the frequency of the driving potential, the resistance and reactance of conductive pathways can be quantitatively determined. Proof-of-principle experiments show 10-nm spatial resolution and ideal frequency-dependent impedance spectroscopy behavior for test circuits connected to electron beam lithographically patterned electrode arrays. Possible applications of NIM include defect detection and failure analysis testing for nanoscale integrated circuits.
