Did you know?
Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H2SO4) and hydrogen peroxide (H2O2). The result of the mixture gives rise to a strong union of two acids called per-hexa-sulfuric acid (H4SO6) that is used to clean organic residues off substrates. Because the mixture is a strong oxidizing … Visa mer Many different mixture ratios are commonly used, and all are called piranha. A typical mixture is 3 parts of concentrated sulfuric acid and 1 part of 30 wt. % hydrogen peroxide solution; other protocols may use a … Visa mer Piranha solution is used frequently in the microelectronics industry, e.g. to clean photoresist or organic material residue from silicon wafers.
