We have a large assortment of 8" wafer chips from a semiconductor company that went out of business. Great for a shelf or desk display. Each wafer is different, you can pick from the assortment we have.
$30 each, discounts for multiple. Storage containers also available.
We do not know specifically what's on these, but the company was dealing with the wireless spectrum and could be possibly with Kyocera or other similar chips.
