Background Art

Single crystal silicon usually refers to a substance composed of arranged silicon atoms. Silicon crystals are widely used in the photovoltaic industry. In order to meet the quality parameters of silicon crystal rods and the shape and size of the next process, the silicon rods need to be initially processed.
