The prediction of characteristics of point defects in silicon crystals is the final goal of numerical simulation of the whole process of growth from the melt, recognized today as a helpful tool in technology optimization. We present an effective numerical model with an accurate description of defect incorporation and evolution in a growing crystal. The model is applied to a 300-mm diameter CZ silicon crystal with an investigation of the sensitivity of the predicted defect characteristics to input parameters.
