For the fans of regular structures among us.

And now we are at about metal-3, with some metal-4 remains visible. Not sure what that contamination spot is about. :D But it certainly affected the planarity nearby.

I am most intrigued by this set of cells not connected to anything else. Same cells found in groups elsewhere. Does anyone have an idea why is this here?

Die ID is now gone too. Always amusing how things just vanish without a trace.

The rest of metal-5 is gone from the centre, and a lot of metal-4 is now missing on the sides.

Some locations still have M5-M4 vias, while others do not. Need to check the progress more often.

And so, another attempt at the same. This is certainly overdone as metal-4 seems to have been attacked in some places, but a marked improvement overall.
Even more interesting, while oxide interference disappeared, some other colours persisted. Silicon nitride?
Easy to confirm how many metal layers we have here.
