QUALITY ESTIMATING METHOD FOR CROPPING A SINGLE CRYSTAL INGOT

摘要

A quality estimating method for cropping a single crystal ingot is provided to improve excess of a sampling number by making a sampling rule for determining a cropping position and a sampling position and the sampling number of the single crystal ingots. An input process is performed to input basic information for determining a cropping position, a sampling position, and a prime position(a). A setting process is performed to set the cropping position, the sampling position, and the prime position according to the basic information(b). A monitoring, analyzing, and storing process is performed to monitor an ingot growth process and analyze and store an X factor(c). A confirmation process is performed to confirm the cropping position and the sampling position by using the cropping position and the sampling position(d).
