Subject: [mems-talk] Ag wet etch

Does anyone have a recommendation for wet etching a 100nm layer of
silver on a glass fiber. Through internet research I have only found a
recipe that calls for NH4OH:H2O2 (1:1) @ room temp, but no etch rate or
any other info. Does anyone have a recommendation. Thanks.
