Germanium Wafer Process


In the germanium wafer production process, germanium dioxide from the residue processing is further purified in chlorination and hydrolysis steps.

1) The wafers are cleaned and inspection. During this process, the wafers are single side polished or double side polished according to custom requirement, epi-ready wafer comes.

2) A germanium crystal is produced via the Czochralski process.

3) The germanium wafer is manufactured via several cutting, grinding, and etching steps.

4) High purity germanium is obtained during zone refining.
