+| s1-3          | 3 min 20% hf\\ 2 min barrier\\ 4 min hcl/h2o2  | misc process issues causing unintended times\\ significant top metal erosion of some sort\\ see stringers floating around  |
+| s1-4          | 3 min 20% hf\\ 2 min hcl/h2o2\\ 4 min barrier  | significant erosion into oxide\\ looks like maybe some wax residue on die?\\ Gentle IPA scrub w/ foam tip removed it       |
+| s1-5          | 2 min 20% hf\\ 2 min hcl/h2o2\\ 4 min barrier  | much more etching\\ lots of transistors exposed\\ keep going at this cadence\\ scrubbed die again to remove residue        |

+| s1-7          | 2 min 20% hf\\ 2 min hcl/h2o2\\ no barrier     | Getting close to done\\ No barrier and no residue\\ Barrier etch must be eating wax                                        |
