摘要： A silicon-wafer processing fluid used for processing a silicon wafer contains a friction modifier containing a nitrogen-containing compound, pH of the nitrogen-containing compound being in a range from 2 to 8 when a mass ratio with water (i.e. nitrogen-containing compound/water) is 1/99. The nitrogen-containing compound is preferably a heterocyclic compound. The silicon-wafer processing fluid restrains an abrasion of abrasive grains rigidly attached to a wire and generation of hydrogen.

摘要： A water-soluble working fluid of the invention is used for cutting a brittle material using a wire saw. The water-soluble working fluid is provided by blending water, alkylene oxide adduct of acethylene glycol, and glycols. The water-soluble working fluid of the invention is capable of providing favorable cutting accuracy when the brittle material is cut using a wire, and thus is suitable for cutting out a large-diameter wafer. The water-soluble working fluid of the invention is especially suitably applicable to an abrasive-grain-fixed wire saw.
