A metod to determine the conductivity dependence versus distance from the surface of a high resistivity semiconductor wafer is discussed (considerated). By one dimension computer calculations it was shown that this inverse problem may be solved by Q-factor measurements of open confocal resonator. The measurements have to made for several frequencies at four positions of the wafer in the resonator waist plane.
