In this work the behavior of Molybdenum (Mo) during chemical mechanical polishing (CMP) is examined. The material removal rates (MRR) were studied by changing not only the chemical (abrasive and oxidizer concentration, pH) but also the mechanical (downforce pressure, platen and carrier speed and polishing pad) parameters. Keywords: CMP Mo, alumina, silica, slurry, hydrogen peroxide
