  • A commercially de-waxer which kinds of solvent after was used to remove a thick organic wax film after polishing process and several steps of SC-1 cleanings were followed for the removal of organic wax residues and particles which requires long process time and high cost of ownership (COO). DIO3 was used to remove organic wax residues too achieve low COO. In this study, 0103 rinsing could use instead of 01 water rinsing. The process time and chemical consumption were reduced by using DIO3.
