Slurry pads with dielectric material

The Optiplane™ slurry platform is a family of advanced dielectric, nitride and polysilicon slurries with tunable removal rates and selectivities that can meet defect reduction requirements and tighter specifications at a competitive cost for manufacturing the next generation of advanced semiconductor devices. WebbThe CMP process in silicon wafer production consists of a mechanical polishing step which utilizes a chemical slurry formulation to remove unwanted conductive or dielectric materials from the surface of the integrated device, achieving a flat and smooth surface upon which additional layers of integrated circuitry are built.

While the pad is spinning, slurry is pumped on to the pad to maintain a sufficient amount of abrasive slurry. Inadequate amount of slurry would result in poor uniformity. Too much slurry would be wasteful. The next concern is the amount of down force needed to achieve adequate erosion rates without compromising uniformity.
