Although silicon remains to be the most widely used material in the wafer manufacturing industry, another type of material is also worth looking into – gallium arsenide (GaAs). However, if you want to enjoy the benefits of brand-new GaAs wafers for a fraction of their price, take a closer look at GaAs reclaim wafers.[video width="1920" height="1080" mp4="http://waferworld.yourdigitalresource1.com/wp-content/uploads/2021/07/waferworld-15sec-headervideo.mp4"][/video]
Since GaAs reclaim wafers are used test and prime wafers, they’ve gone through the stringent process of being stripped of their thin layers of film. To get rid of all of the unwanted patterns and signs of surface defects, these wafers are carefully re-polished until it achieves the same level of standards as a regular wafer.
Once the reclaiming process has effectively restored the gallium arsenide surface to a usable grade, the wafers become thinner than virgin wafers. It’s important to note that a single wafer can go through multiple reclaim cycles until they become too thin to be used. Before they need to be replaced, gallium arsenide reclaim wafers offer the same advantages as brand-new wafers and are also suitable for most of the same uses.
Gallium arsenide reclaim wafers offer superior electronic properties, high carrier mobilities, low resistive device parasites, highly resistive properties, and their ability to resist radiation damage. These qualities make them the perfect choice for testing purposes.
The process of reclaiming partially and completely processed gallium arsenide wafers can cause you to increase cost savings. Typically, reclaim wafers are less than one-third to one-fourth of the cost of brand-new prime test wafers. Additionally, they’re also cost-effective for wafer sizes that range within 100-mm through 300-mm.
