CMP CoO reduction: slurry reprocessing

Thomas Frederick Allen Bibby; John A. Adams; Karey Holland; Gerald A. Krulik; Paul Parikh

Abstract Initial results of chemical mechanical planarization (CMP) of 8 inch diameter thermal oxide (TOX) and TEOS sheet film semiconductor wafers using CMP slurry that have been reprocessed are presented. The slurry is reprocessed in an on-line system that has been fitted onto an IPEC Planar model 472 CMP system. Slurry consumption during the testing was at one-fifth of normal CMP slurry consumption for the system. CMP results showed no differences between wafers polished with 100% fresh slurry and those polished with reprocessed slurry.
