Germanium Wafer Process

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

1) High purity germanium is obtained during zone refining.

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

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

4) 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.

5) The wafers are packed in single wafer containers, under a nitrogen atmosphere.


Application:

Germanium blank or window are used in night vision and thermographic imaging solutions for commercial security, fire fighting and industrial monitoring equipment. Also, they are used as filters for analytical and measuring equipment, windows for remote temperature measurement, and mirrors for lasers.

Thin Germanium substrates are used in III-V triple-junction solar cells and for power Concentrated PV (CPV) systems
