    摘要: A system and method for measuring capacitance between a probe and a semiconductor sample, which may be useful in the field of scanning capacitance microscopy (SCM). The present invention also includes a method for analyzing measured capacitance data by subtracting any changes in capacitance that are due to changes in long-range stray capacitance that occur when the probe assembly is scanned.

    摘要: A method for measuring nm-scale tip-sample capacitance including (a) measuring a cantilever deflection and a change in probe-sample capacitance relative to a reference level as a function of a probe assembly height; (b) fitting out-of-contact data to a function; (c) subtracting the function from capacitance data to get a residual capacitance as a function of the probe assembly height; and (d) determining the residual capacitance at a z-position where the cantilever deflection is zero.
