One of the most challenging aspects of the CMP process, particularly in applications like Shallow Trench Isolation (STI), is the difference in relative removal rates of the different materials that are being polished. A certain amount of over-polish is required to clear oxide on top of the nitride, however, this over-polish may also lead to significant problems like dishing and erosion (introducing additional topography after the film has been planarized). This work formulates a methodology to predict how this additional topography is modulated by incoming layout properties introducing a parameter to accurately characterize line and space width on a layout with random geometric shapes.enginfo:eu-repo/semantics/restrictedAccessConference paper5039838900033831310000810.1149/05039.0083ecstChemical-mechanical planarizationShallow-trench isolationOptimization2-s2.0-84885696567
