Purity silicon measuring instrument, silicon sorting device, and silicon purity measurement method

摘要

Purity silicon instrument of preventing metal contamination of silicon, can be measured within the purity silicon, silicon sorting device, and a silicon purity measurement method. The magnetic field generator 14 for generating a measured magnetic field flux so as to transmit the inspection table, inside of silicon was placed on the test bench, a silicon purity measurement device 10, a magnetic field after the interruption of the coil magnetic field it is configured to identify the purity of the silicon inside the degree of attenuation and a determining section 36 of the attenuation degree, the determination unit 36 ​​has determined.
