While wafers are found in almost every type of technological device, sometimes they can be quite expensive. Just like how car companies have used or pre-owned cars that they offer to people that might not want to spend money on a new car, the wafer industry offers something similar. Reclaimed wafers are previously used wafers that have been restored to function like a new one would. Let’s take a look at the process that goes into GaAs reclaim wafers.
When previously used wafers come in, the first thing that is done is the inspection. They are inspected in order to see first off if they can be refurbished and then what needs to be done to get them turned around. They are also sorted by type, thickness, and resistivity.
After the inspection process, each wafer is stripped and etched. This is done to remove patterns, scratches, and other surface defects. The result is a clean, high-quality wafer that is ready for polishing.
The polishing process takes place after the wafer has been adequately cleaned. Each wafer is polished based on their specific specification and use.
The wafer then goes through a cleaning process. This is done to make sure that there are no imperfections left on the surface of the wafer.
At the very end of the process, a final inspection is performed to verify that the finished wafers fully comply with customer standards and specifications.
