The optimization of the crystal surface temperature distribution is performed for single-crystal growth in the Czochralski process. In the optimization problem, we seek an optimal solution in the sense that the index of crystalline defects is minimized while the single-crystal growth rate is maximiz
## Abstract Modification of weight signal of LEC, VCZ crystal growth processes based on the knowledge of the weight signal in the past during the pulling process was considered. This modification is necessary for development and improvement of the direct automated weight control in these techniques
