The Czochralski method is a technique used to grow single crystals from a molten material. In this process, a seed crystal is dipped into the molten substance, and as it is slowly pulled upward and rotated, the material solidifies around the seed, forming a larger crystal. This method is commonly used for materials like silicon and germanium. This technique is essential in the semiconductor industry, as it produces high-purity crystals needed for electronic devices. The quality of the crystals grown using the Czochralski method directly impacts the performance of components such as transistors and diodes.
