Patent ID: 6842029

Claim:
A semiconductor wafer multi-probe assembly, comprising: a chuck assembly configured to receive a surface of a semiconductor wafer; a multi-probe holder having a plurality of probes, each of the plurality of probes having an elastically deformable conductive tip movable into contact with (i) a front surface of a dielectric formed on a front surface of semiconducting material forming the semiconducting wafer or (ii) a front surface of the semiconducting material; and a means for selectively applying an electrical stimulus to each elastically deformable conductive tip, for measuring a response to the electrical stimulus, and for determining from the response at least one electrical property of the dielectric and/or the semiconducting material, wherein when each elastically deformable conductive tip is in contact with the semiconducting material, said means applies a capacitance-voltage (CV), a capacitance-time (Ct), a conductance-voltage (GV) or current-voltage (IV) type electrical stimulus and measures the respective CV, Ct, GV or IV response of the semiconducting material to the electrical stimulus.
