6"/100mm KL10931_CA PROCESSED GOLD PURE SILICON WAFER ETCHED DEVICES GOLD LAYER

THE PHOTOS SAY IT ALL………

For sale is 1 (one) beautiful 6" or 150mm etched silicon wafer. This is a wafer marked KL10931_CA and is an overall golden-yellow colour as you can see in the photos - see the photos of the actual item you will receive. The front of the wafer is etched with circuit patterns as shown and the rear of the wafer has a beautiful purple/blue satin finish. I think the gold colour comes from the final metal layer so it is probably pure 24K gold but hey I am no expert.

Look at the structures you can see even under a cheapo USB microscope. Imagine how this would pop under a real microscope!

THE WAFER IS NOT CRACKED OR CHIPPED

These are manufacturing pulled wafers - 100% perfect wafers would cost in excess of $100 (US Dollars) and in any case would not be for sale on eBay as the manufacturer always destroys any surplus wafers.

There will be some imperfections and micro scratches and this is just part and parcel of buying used VINTAGE wafers - you gotta live with it!!

The gallery photo shows how this wafer looks under LED and under my small cheapo microscope lighting - stunning eh?

This is one of the weirder wafers I have seen in along long time!!

Wafer will be well packed with plenty
