Removing Subsurface Damage by Chemical Mechanical ...

It also removes stress and surface damage. Polishing works by putting vacuum pressure on a wafer. It is slowly put in contact with a rotating platen that is fitted with a polishing pad. Meanwhile, a diamond liquid slurry is sprayed on the polishing surface. Together, the polishing pad and slurry grind away imperfections.
