Czochralski process

[chə′kräl·skē ‚präs·əs]
(crystallography)
A method of producing large single crystals by inserting a small seed crystal of germanium, silicon, or other semiconductor material into a crucible filled with similar molten material, then slowly pulling the seed up from the melt while rotating it.
