2 2" Silicon Wafer American Microsystems Gould Atari UHAST Tested Extremely Rare

Description

I have here 2 Extremely Rare 2" American Microsystems / Gould Semiconductor Silicon Wafer in Case that has gone through UHAST Testing from sometime in the Early 1980's.
This is a very interesting Wafer because most wafers do not come with any indication of testing or what has been done to it, so this is definitely an interesting/rare addition to any chip/wafer collector's collection.
I initially thought that "0684" was a date code, but a second wafer I have proves that to most likely be impossible as "36?" was the other "date code."  This was purchased from an Engineer who worked for Gould Semiconductor in the 1980's, which was purchased by American Microsystems.  This Engineer said he found this and another wafer in the back of his desk inside the case, when he was leaving American Microsystems.  The Engineer said that these most likely would have been from an "Atari Order," as they were producing many chips for the Atari back then.

"UHAST" Stands for
Unbiased Highly Accelerated Stress Test

Autoclave/Unbiased HAST
Autoclave and Unbiased HAST determine the reliability of a device under high temperature and high humidity conditions. Like THB and BHAST, it is performed to accelerate corrosion. Unlike those tests, however, the units are not stressed under a bias.

If you have any questions please do not hesitate to ask.
I will be listing many unique, rare, one-of-a-kind, vintage CPU, Computer Chips, Silicon Wafers, and other parts in the following weeks, so if there is any interest or inquiry into something I might have, please don't hesitate to ask!
Thank you for your time with viewing my listing, I appreciate it. I hope you have a great day!
NOTE:  Handling time is set to 10 days because I normally end up having buyers who want more than 1 item, so a few days can go by before the full transaction is completed; however, the handling time set for each item has to be obeyed or else penalties happen to me, so I set the handling time to a time that shouldn't cause problems.  I have been recently notified(10/24/22) that some buyers are concerned about the long handling times so I want to make everyone completely aware of the situation.
After THE FULL Transaction is complete(the buyer is done choosing listings to purchase, and ready for shipment), I normally try to ship the day of completion or the next day(depending if transaction completion happens early enough in the day and on a weekday), but 2-3 regular days(not business days) would be the maximum handling time.  I do not want buyers to have to wait for their product after purchase, I just want to make sure buyers have selected everything they want to purchase, before I ship, as most of my buyers thus far have wanted more than 1 item, while at the same time make sure I do not get penalized, because even if a buyer is okay with waiting, I have to obey the times set by the site.  Thank you for your understanding, and thank you for your time with viewing my listing, I really appreciate it.  If you have any questions at all about this issue, or anything else I can answer for you / help-you-with, please do not hesitate to ask.  I am here to make the Buyer's experience completely satisfactory, so let me know if there is anything I can do for you!  I hope you have a fantastic day!
