Abstract
This paper demonstrates and realizes that the Chemical Mechanical Polishing (CMP) oxide slurry could be recycled to CMP process again. By the slurry recycling process, 90% waste slurry could be reclaimed and also over 90% wastewater could be recycled and reuse in integrated circuits (ICs) process. The demonstrated reclaimed slurry show compatible removal rate (R/R) and the same uniformity (U%) of R/R. Also the compatible R/R profile and defectives level.
