Abstract
The present invention provides a method for calculating the liquid-solid interface morphology during growth of the ingot. The method comprises providing a wafer, selecting plural sampling locations on the wafer and detecting electrical resistivity at the plural sampling locations, calculating height differences between the sampling locations based on the detected electrical resistivity, and illustrating the morphology of the liquid-solid interface based on the calculated height differences. The method of the invention has advantages including easy operation and low cost.
