A Germanium wafer is one of the most popular elemental semiconductors. It is known for its outstanding crystallographic characteristics and its unparalleled electrical features. If you’re thinking about using Ge wafers for your next project or in your business, then it’s good to know more about this type of wafer. Read on to know more about the Ge wafer production process and its applications:

Ge Wafer Production Process

The manufacturing process of Ge wafers includes a number of specific procedures that can be classified into four categories:

  • Ge manufacturing
  • Photolithography
  • Oxidation
  • Diffusion and ion implantation.

The process starts with a germanium dioxide filtered through the chlorination and hydrolysis process. Next, in order to produce highly pure Germanium, it goes through the zone refining process.

Czochralski Method

The Czochralski method is used to produce a Germanium crystal which will then undergo cutting, grinding, polishing, and etching. After that, the wafers go through cleaning and inspection before it is packaged in a single wafer container, in a nitrogen atmosphere-filled room. The Ge wafer produced to act as a substrate for various devices, which allows other components to be fabricated in and on the wafer.

Ge Wafer Applications

A Germanium wafer is widely used in III-V triple junction solar cells, infrared optics, power concentrated PV systems, and sensor applications. A Germanium window is also utilized in thermographic imaging solutions and night vision for industrial control equipment, commercial security, and firefighting. It is also employed in filters for analytical, mirrors for lasers, gauging equipment, and remote temperature calculation.
