#nakeddiefriday

Hello, wonderful people. Taking a break is good, so I am taking a couple moments to write the #nakeddiefriday post of the week.

Today we have this interesting sample. Yes, it has certainly seen better days; been sitting in a queue for a real while now. This is again a smartcard chip without a name to it. I believe this to be fabbed by Samsung, and be rather old. The chip is built using poly-gate CMOS with 3 metal layers; later processes moved to a higher layer count.
