Czochralski Silicon (Straight Pull Silicon)

Product Overview:
Czochralski silicon (or straight pull silicon) is a high-quality silicon single crystal material produced using the Czochralski method. In this process, polycrystalline silicon is melted, and a seed crystal is used to grow a single crystal with a highly ordered atomic structure. Due to its high purity and density, Czochralski silicon is widely used in the manufacturing of semiconductor devices and integrated circuits. The production process is strictly controlled to ensure that the material's optical and mechanical properties meet high standards, making it a key foundational material in many high-tech applications.
