[18p-D103-22] Measurement of carbon concentration in silicon crystal (XIV) Fabrication of reference sample and block gauge down to 1013cm-3 for IR measurement
Keywords:FZ silicon crystal, carbon concentration measurement, infrared absorption
Reference samples for IR measurement of carbon concentration in silicon were fabricated by electron irradiation from the samples provided from the leading polysilicon companies in the world. Substitutional carbon concentration ranged from 1E+15 to 1E+13 cm-3. Both companies and us shared the sample sets to improve the measurement sensitivity and accuracy.
