Beschreibung
Zusammenfassung:	A solution for semiconductor wafer dicing is disclosed. The solution suppresses the adherence of contamination residues or particles, and reduces or eliminates the corrosion of the exposed metallization areas, during the process of dicing a wafer by sawing. The solution comprises at least one organic acid and/or salt thereof; at least a surfactant and/or at least a base; and deionized water, the composition has a pH is equal or greater than 4. The solution can further comprise, a chelating agent, a defoaming agent, or a dispersing agent.
