SNF is open under New Normal Rules. ANY shadowing must be coordinated with SNF staff first.
BOE is an HF based etchant that is buffered to reduce impact to resist. This particular formulation is quite concentrated in HF and should only be used if needed. 20:1 BOE is a safer alternative for instances where there is not a lot of material to etch.
