8"/200mm Pure Silicon Wafer Etched Devices Ricoh Device Pink Satin Reverse:
THE PHOTOS SAY IT ALL……… AN ABSOLUTE MACRO PHOTOGRAPHERS DELIGHT
For sale is 1 (one) beautiful 8" or 200mm etched silicon wafer. This is a RICOH wafer and has a device name/number that I cannot make out with my cheap microscope -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 is a beautiful light pink satin finish
THE WAFER IS NOT CRACKED OR CHIPPED
These are manufacturing pulled wafers - 100% perfect wafers would cost in excess of $300 (US Dollars) and in any case would not be for sale on as the manufacturer always destroys any surplus wafers.
will be some imperfections and micro scratches and this is just part
and parcel of buying used VINTAGE wafers - you gotta live with it!! These wafers are as pretty near perfect as you will see on
The gallery photo shows how this wafer looks under Halogen lighting and under my small cheapo microscope lighting - stunning eh?
Wafer will be well packed with plenty of bubble and space to breathe - posting is by Registered Airmail with a tracking number that can be used to trace the item._gsrx_vers_476 (GS 6.4.4 (476))
