Modeling of point defect formation in silicon monocrystals
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.
