Silicon nitride coated crucibles for holding melted semiconductor material and for use in preparing multicrystalline silicon ingots by a directional solidification process; methods for coating crucibles; methods for preparing silicon ingots and wafers; compositions for coating crucibles and silicon ingots and wafers with a low oxygen content.

Coated crucibles and methods for applying a coating to a crucible

Methods and systems for evaluation of wafers are disclosed. One example method includes illuminating a multi-crystalline wafer according to a plurality of lighting parameters, capturing a plurality of images of the multi-crystalline wafer, stacking and projecting the plurality of images to generate a composite image, analyzing the composite image to identify one or more grains of the multi-crystalline wafer, and generating a report based on the analysis of the composite image. The multi-crystalline wafer is illuminated according to a different one of the plurality of lighting parameters in at least two of the plurality of images.
