Edge roll off
WebThe edge roll-off error is caused by the edge effect of the polishing tool, i.e. the change of the pressure distribution in the edge area gives rise to the nonlinear removal behavior. Various models have been developed to describe the edge pressure distribution [5–8]. WebNov 1, 2024 · However, the surface flatness significantly deteriorates near the wafer edge because edge roll-off (ERO) occurs in the polishing process as the final stage of wafer …
