Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for determining a coefficient for evaluating a nitrogen concentration in a silicon crystal, which precisely determines an impurity nitrogen concentration in the silicon crystal.  <P>SOLUTION: A plurality of silicon crystals having different nitrogen concentrations are prepared. Each silicon crystal is heated at a first temperature in order to bring an in-crystal defective reaction into its quasi thermal equilibrium state, and an infrared absorption spectrum of each silicon crystal is measured while keeping an in-crystal defect concentration in the quasi thermal equilibrium state, and a first absorption peak value resulting from NN pairs and a second absorption peak value resulting from NNO complexes are acquired. For each silicon crystal, a concentration of the NN pairs is determined by multiplying an absorption efficient acquired from the first absorption peak value by a first scale factor. Then, a concentration of the NNO complexes is determined by subtracting the concentration of the NN pairs from each nitrogen concentration. The concentration of the NNO complexes and an absorption efficient acquired from the second absorption peak value from the plurality of silicon crystals are used to determine a relation between them.  <P>COPYRIGHT: (C)2007,JPO&INPIT
