In this paper, a new method is described for determining the near surface electrically active dopant density (NSURF). This is a powerful new method that allows for the monitoring of Activation for USJ Structures. The technique uses a non‐penetrating, non‐damaging probe that elastically deforms to form a contact on the bare or native oxide covered surfaces of USJ structures. Advanced Capacitance‐Voltage (CV) methods are used to determine the electrically active dopant, not carrier, density. The technique and physics will be described in detail along with several case studies.
