www.cityu.edu.hkSilicon nitride is a barrier to sodium diffusion, is nearly impervious to moisture, and has a low oxidation rate. The local oxidation of silicon (LOCOS) process also uses silicon nitride as a mask. The patterned silicon nitride will prevent the underlying silicon from oxidation but leave the exposed silicon to be oxidized.

Some metals etch in BOE (Titanium, Aluminium) some do not (Chromium, Gold, Platinum). You can mask a BOE etch with photoresist for a short etch (20 mins or so). If you etch longer, the photoresist will start to peel off.
