Chemical mechanical planarization (CMP) slurries for semiconductor wafer polishing: the hidden liquid infrastructure flattening the AI chip economy one nanometer at a time

A modern AI chip is not only built by lithography, deposition and etching. It is built by removing material with controlled violence. Every 300 mm wafer carries nearly 70,000 square millimeters of silicon area, and every extra metal layer, dielectric trench, contact plug and bonding surface adds another height mismatch that must be reduced to nanometer-level flatness. That is where Chemical...
