wafer in collection?

[naked1300]

i have one question to you all. I think some of you are also collecting
wafer's. So my question is if anyone has an 1" and 1,5" ?? I think they
are really hard to get

I have only managed to get Russian 1" wafers

my 1" wafers are unpolished

I have 4 2" wafers, one blank, one with tiny structures, and two with larger visible structures. I also have one 6" wafer, with two very small chips. I think you can order silicon wafers new. I used to use them as sample substrates in grad school. Some spammers still email me with wafer deals once in a while.

These wafers come with a drum type containers with slots to slide them in, like an old-fashion floppy or CD container

I didn't know if they were of any collector values. I got them from a trade with a bunch of other CPUs

I have a couple of wafers in my collection (with and without structures), and also an exposure mask for 1" USSR wafers.

I'll post some pictures later.

I have a 4" Quartz chip wafer with dies from an old Motorola plant that closed in New Mexico. (I have spares of this if anyone is interested in a trade).
I also have a 6" silicon Wafer with Motorola chip dies that I got from my brother as a gift.
