发明名称 Method for wafer dicing
摘要 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 greater than 4. The solution can further comprise a chelating agent, a defoaming agent, or a dispersing agent.
