Patent ID: 8580656

Claim:
An apparatus for wafer dicing comprising: a wafer containing plurality of integrated circuits; a dicing saw; and a dicing solution for wafer dicing consisting essentially of: at least one dicarboxylic acid and/or salt thereof; at least one hydroxycarboxylic acid and/or salt thereof or amine group containing acid; a surfactant selected from the group consisting of phosphate esters branched alcohol ethoxylate based surfactant; alkyldiphenyloxide disulfonic acid based surfactant having a structure of: wherein R is an alkyl group having 10 to 12 carbon atoms; dodecyl benzene sulfonic acid (DDBSA) based surfactant having a structure of: secondary alkyl sulfonic acid based surfactant having a structure of: wherein 10<m+n<14; and combinations thereof; and the remainder being substantially deionized water; wherein the dicing solution is fluoride-free and having a pH of about 1 to about 4; and the dicing solution is effective in inhibiting adherence of the contamination residues to exposed metallization areas and the corrosion of the exposed metallization areas.
