TSMC Photomask (Taiwan)

These are used to make wafers, usually destroyed and disposed afterwards so obviously no one can just duplicate the chips.

Sad since they are lovely when photographed.

Here's shooting info/equipment:

Nikon Rayfact OFM20119MN lens, or the Printing-Nikkor 95mm F2.8 at 2x, retro.

This could be a nice resolution tester, for also CA and the such, but they are extremely scarce. Not many make it out of the factories.

PM me if you have a photomask for the Intel i9-9900k, i9-10900k, or the AMD Threadripper series. I'll take it... :D :D :D

Wouldn't the details of this be five to ten times coarser than the detail on the chip itself? I would think the chip would be a better resolution target than the mask, at least for higher magnifications.
