COPPER BARRIER CMP SLURRIES for METAL REMOVAL

Ferro is a leading global manufacturer of optimized high-purity copper barrier slurries designed to deliver optimal performance in metal CMP (chemical mechanical planarization) applications.

Copper Barrier CMP Slurries for Metal Removal
The Ferro product line of copper barrier cmp slurries provides a wide range of aqueous copper barrier slurries designed to remove the barrier metals that are exposed following copper clearing. Our copper barrier CMP slurries achieve optimal metal CMP removal rates, resulting in decreased cost of ownership and increased productivity using existing equipment and space.

SN4501 copper barrier CMP slurries feature a tunable removal rate for copper barrier and oxide with linear response to downforce.

Selectivity is also tunable for copper/TEOS which allows a good oxide loss control and results in low surface roughness.
