AQRUM is an inorganic additive used for dicing during the semiconductor production.
Dicing requires semiconductor wafers (especially those of large diameter) to be exposed to cutting water (ultra pure water) for a long time and a small amount of aluminum ion elutes from the cutting surface of wafers. A surfactant is used as a dicing additive to minimize this elution problem. AQRUM is the inorganic dicing additive developed under the new concept of utilizing ionization to solve such problem of aluminum ion elution from semiconductor wafers during dicing. Conventional organic surfactants need waste water treatment after dicing. AQRUM, which is inorganic, can eliminate waste water treatment. AQRUM is truly an environmentally friendly additive. Available in a 10 liter pure bottle.
