Measurement of Low Concentration Nitrogen in Czochralski Silicon by Infrared Absorption Spectroscopy
Nitrogen in Czochralski silicon mainly forms pair with oxygen at low concentration, in contrast to forming NN pair at high concentration. To measure nitrogen concentration in NO pair form, local vibration modes of NO family such as NO, NOO and NOO2 were examined. By removing LVMs by NN family and ox...
