 +| 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       |
