WebA new type of BOE 7:1 in our portfolio is the Buffered Oxide Etch with Surfactant. Used for etching of SiO2. Due to the higher PH value in contrast to unbuffered HF it gives better results in combination with photo resists. The etch rate on SiO2 is (depending on temperature and SiO2 morphology) in the range of 70-90 nm per minute.
