Hi, I'm new here and it is amazing all information i can see around..
And i will start with my first question...
I do have a 4" Silicon wafer ( See photo ) , under microscope it reads:
Hp
Made in USA
Corvallis
The date is not clear, i guess it is from 1986 and an umbrella like logo.
anybody knows more about this ?
Thanks!!!
