Abstract

We carried out calculations to investigate the influence of thermal conductivity of the wall of a crucible on thermal stress and dislocations in a silicon ingot during a solidification process using a three-dimensional global analysis. It was found that the mc interface shape and the temperature gradient in a silicon ingot have significant influence on thermal stress and dislocations due to different thermal conductivity of the wall of a crucible. Therefore, we should control not only the mc interface shape, but also temperature gradient in a silicon ingot in order to reduce thermal stress and dislocations in a silicon ingot during a solidification process.
