The process of transforming an element into thin wafers with a damage free, mirror-like, clean surface is no easy task. It requires a series of steps.
Here are the 5 steps in the germanium wafer production process:
1) Highly pure germanium is attained during zone refining.
2) The Czochralski process transforms the element into a germanium crystal.
3) The crystal is manufactured into a wafer through the process of cutting, grinding and etching.
4) The Ge wafers are cleaned and inspected. This step requires the wafers to be polished on either one or both sides, depending on the customers needs.
5) The high-quality wafers are packed under a nitrogen atmosphere in single wafer containers.
