The MOL processes are introduced to connect the individual transistors. WebCMP is used to reduce the topography down to the silicon nitride CMP-stop layer deposited on the active areas. An important aspect of the process is that it needs to produce minimal dishing in the trench oxide after an overpolish step to remove the oxide from the active area nitride. The selection of the polishing slurry is therefore critical. david andrews reno nv
