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.
