Aaand there is no next deprocessing step, because I managed to lose this sample too while trying to get metal-1 off. Thus, the thread ends here. This made me very sad, and pointed to an obvious area needing improvement in my process.
I hope you enjoyed looking at the construction of a more complex chip in detail as much as I did taking these images. As always, I will appreciate any and all support to offset the costs of consumables required to do this work.
I wish you all a great end of this week. Stay safe, stay healthy, and I hope to see you all next Friday.
