  • METHOD AND CRUCIBLE FOR PRODUCING PARTICLE-FREE AND NITROGEN-FREE SILICON INGOTS BY MEANS OF TARGETED SOLIDIFICATION, SILICON INGOT, AND THE USE OF THE CRUCIBLE
    Publication number: 20220213616
    Abstract: The present invention relates to a method and to a crucible for producing particle-free and nitrogen-free silicon ingots by means of targeted solidification, in which method a crucible is provided, the inner surface of the crucible having a coating containing SixNy over its full surface or at least in regions, which coating is coated with a protective layer containing SiOx in order to reduce or prevent the introduction of nitrogen and SixNy particles into the silicon. The invention also relates to a silicon ingot, which is virtually free from nitrogen or SixNy particles.
