Thank you for adding this bulletin board to your web site. I wonder if SRP has limitations for measuring high resistivity substrates. I am particularly interested in accurate measurements of resistivity of float zone silicon with resistivity over 1000 Ohm-cm (which corresponds to the doping levels below 1e13 cm-3). Will the SRP technique work at all on such wafers, can one expect higher error margins? Can you estimate the error - 1%? 10%? 100%?
