Intersil 4" Silicon Wafer Vintage 1984 Extremely Rare

Description

I have here an Extremely Rare 4" Intersil Corporation Silicon Wafer with Date 1984.
I tried taking a picture of the model/item number that I see, but it is pretty hard to see the info.  It looks like the value is "3P3R43(3 or B or 8).  I will look under the scope again and write down the actual value, but I'm unsure how good of a picture I will be able to get if I try again.
The original Intersil, Inc. was founded in 1967 by the Swiss physicist
Jean Hoerni
to develop digital watch
Integrated Circuits
(ICs).

The European subsidiary Eurosil was originally partially funded by SSIH, a Swiss watch company. Later-on, Intersil had a development contract with the Japanese company Daini Seikosha and became supplier of low-voltage
CMOS
watch ICs for
Seiko
.
[6]
When
microprocessors
emerged to the market in the 1970s, Intersil participated with its
12-bit
IM6100
, which was the first microprocessor produced in CMOS technology and emulated the
PDP-8
instruction set.
In 1988, Intersil was taken over by
Harris Semiconductor
, which had offered the IM6100 as
second source
. Harris combined these activities with the semiconductor divisions of Radiation Incorporated,
General Electric
and
RCA
they had taken over before. In 1999 Harris spun off its entire semiconductor division and Intersil Corporation was created
[7]
with the largest IPO in American semiconductor industry history.
[8]
The second Intersil Corporation is a different company from the original Intersil, Inc.
Next to digital circuits like microprocessors and memories like the 1k-bit CMOS RAM IM6508 and CMOS EPROMS IM6604/IM6654 Intersil designed famous analogue ICs like the
ICL8038
waveform generator. A creation of Intersil (as Harris Semiconductor) is the
PRISM
line of
Wi-Fi
hardware: that group of products was sold to
GlobespanVirata
in 2003, and maintained by
Conexant
. Intersil is the manufacturer of the
RCA (CDP)1802
microprocessor
(also known as RCA COSMAC),
[9]
a
CPU
traditionally used in space applications.
In the 2000s, Intersil established market leadership in Vcore

power management for PCs, switching and buck boost regulators for industrial and consumer power systems, and radiation hardened analog and power ICs for military and commercial applications.

Open to offers.
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!
