Buying new wafers for testing and qualification can get expensive. If you want the benefits of brand-new test wafers without paying full price, InP reclaim wafers can be a great option for you. Here are the things you need to know about reclaim wafers:
Wafer recycling is a process of removing nearly all semiconductor films. This process does not affect the wafer’s thickness which allows the wafers to be further processed and re-used.
InP reclaim wafers are recycled prime and test wafers which have been polished to get rid of patterns and surface scratches. InP reclaim wafers perform the same with normal test wafers despite the fact that they are a little thinner compared to virgin wafers.
The process begins with an ocular inspection. This makes sure that the wafers have no scratches or chipped edges. Its flatness is then measured to make sure that it is still suitable for further processing. After this, the wafers go through a chemical stripping process to remove the thin films present in the wafer. Polishing, cleaning, washing, and rinsing with pure deionized water is also done before it is dried.
Prime wafers have immensely strict specifications for resistance, particle count, and flatness. This type of wafer is highly uniform which makes it a device-quality wafer. Its exceptional quality and performance make it one of the best wafer grades.
Test wafers are wafers that were not able to qualify as prime wafers. They are considered to be a cost-effective alternative to prime wafers. Test wafers are commonly used to run marathons of equipment testing and for high-end R&D.
InP reclaim wafers offer the same performance as new test wafers do at a lower price. If you’re looking for a way to cut costs, quality reclaim wafers is the solution you’re looking for.
