The electronics industry builds everything from smartphones to heart monitors, and all of these systems depend on high-quality microchips. During manufacturing, water is used to rinse wafers and chips, and any ionic residue left behind changes the electrical behaviour of the device.
Because water naturally carries dissolved salts that conduct current, it must be polished to the highest purity before it touches a wafer. XRESIN ultrapure water grades polish the rinse water to maximum resistivity, removing sodium, calcium, boron, silica and other contaminants that would otherwise compromise yield.
These systems typically combine strong-acid cation, strong-base anion and mixed-bed polishing stages. Low total organic carbon and minimal leachables are essential, since even trace organic release can affect advanced nodes.
