Description
Other Notes
Hydrofluoric acid is an aqueous solution of hydrogen fluoride (HF). It is a highly corrosive and toxic acid capable of dissolving many materials especially oxides and silicates. In its semiconductor-grade purity it is manufactured under strict conditions to eliminate metal particle and organic contaminants typically meeting electronic grade specifications
Application
1) Oxide Etching 2) Cleaning and Surface Preparation
