Abstract:The calculation formula for determination of nitrogen in CZ-Si grown under nitrogen atmosphere by infrared absorption lines related to nitrogen at 963, 996, 1 018 and 1 027cm-1was given and the samples were measured with RSD 5%~20%. This method eliminated the deviation caused by using only 963cm-1in CZ-Si.
Key words: silicon nitrogen infrared absorption spectrometry
