I think you linked to a flip chip---you would expect a mirror finish from the bulk silicon side.

- opencl 8y agoAh yes you're right of course. Has there been anything in the past few years made on modern processes with the die actually visible? Desktop/laptop CPUs and GPUs have all been flip chip for at least the past decade, mobile SoCs are package on package, most other stuff is encased in plastic.
- pantalaimon 8y agoder8auer did flip the Zen dies in the Threadripper over and ground them down to look what's inside. The video gives a good impression of the dimensions of the die and the structures inside. https://youtu.be/N-uKQ6RfUdk https://youtu.be/N-uKQ6RfUdk
- madengr 8y agoSome of the RF processes. The HMC6300 is a mmWave flip chip with visible (to the eye) structures. Even then, it’s limited to passive structures, and maybe the PA output transistors.
