Chemical-Mechanical Polishing (CMP) is a critical process used in semiconductor manufacturing to achieve flat surfaces and precise feature definitions on wafers. It combines chemical and mechanical forces to remove excess material and improve surface quality. Recently, it has been noted as a significant missing step in certain production processes, highlighting its importance in the overall fabrication workflow.

“Another significant missing process step is Chemical-Mechanical Polishing or CMP. CMP combines the mechanical action of a grinding pad with a reactive chemical slurry to grind down layers of material to produce a very flat and level surface. Since that slurry is liquid, it cannot be used in microgravity.”
