Jun 24, 2020 · 7.1.3 Company A Buffered Oxide Etch (BOE) Production Capacity, Revenue, Price and Gross Margin (2015-2020) 7.1.4 Company A Main Business and Markets Served 7.2 Company B What will be the effect of etch rate if I use expired Buffered Oxide Etchant (BOE) bought ready-made from Microchemicals? BOE is made out of NH4F and HF in a certain ratio (e.g. 7:1 or 10:1 Buffered Oxide Etchant • FUJIFILM Buffered Oxide Etchantsare silicon oxide etchants formulated from high purity 49% Hydrofluoric Acid and high purity 40% Ammonium Fluoride. •Formulations are available in standard NH4F:HF ratios or made to customer specification. •Stringent control of both hydrofluoric acid and ammonium fluoride Summary Buffered Oxide Etch (BOE) is a mixture of HF and NH4F in different proportions. 6:1 BOE etching means that 40% NH4F: 49% HF = 6:1 (volume ratio) is mixed. HF is the main etchant and NH4F is used as a buffer. SMFL Thin Film Wet Etch Rates: These etch rates are intended as a guide. Actual etch rates will vary, please verify before use.
