Abstract: PURPOSE: A method for measuring an optimum oxygen concentration having correlation between 300 mm semiconductor wafer measuring apparatuses is to allow wafer measuring apparatuses to have a correlation. CONSTITUTION: A method for measuring an optimum oxygen concentration having correlation between 300 mm semiconductor wafer measuring apparatuses comprises the steps of: withdrawing a double side polished slug from an ingot and a double side polished wafer placed most adjacently to the slug; measuring an oxygen concentration of the double side polished slug; deciding the measured oxygen concentration value as a real oxygen concentration value; measuring an oxygen concentration of the double side polished wafer; designating the measured oxygen concentration value as a real oxygen concentration value; and performing a quality guarantee to confirming whether the oxygen concentration value of the double side polished wafer is within a necessary range.
