Buffered Oxide Etch, BOE 7:1 Buffered Oxide Etch, BOE 7:1 with Surfactant. We supply buffered hydrofluoric acid = BOE 7:1 (HF : NH 4 F = 12.5 : 87.5%) in VLSI-quality, which is the usual purity grades applied in semiconductor processing and micro-electronics. A new type of BOE 7:1 in our portfolio is the Buffered Oxide Etch with Surfactant. Learn more about Buffered oxide etch (7:1), VLSI™, J.T. Baker®. We enable science by offering product choice, services, process excellence and our people make it happen. Buffered oxide etch (BOE), also known as buffered HF or BHF, is a wet etchant used in microfabrication. Its primary use is in etching thin films of silicon dioxide (SiO 2) or silicon nitride (Si 3 N 4). It is a mixture of a buffering agent, such as ammonium fluoride (NH 4 F), and hydrofluoric acid (HF). Research Restart: On 7/6/20, we welcome back external orgs! 1 Buffered oxide etch . Preferred Short Name: 6:1 BOE. Chemical Formula: 34% NH 4 F, 7% HF, 59% H 2 O.
