The Czochralski process is a method used to grow single crystals, primarily for semiconductors like silicon. In this technique, a seed crystal is dipped into a molten material, and as it is slowly pulled upward and rotated, the material solidifies around the seed, forming a larger crystal. This process is crucial in the production of high-purity crystals, which are essential for electronic devices. The Czochralski process allows for precise control over the crystal's properties, making it a key technique in the manufacturing of integrated circuits and other advanced technologies.
