What it is

General reference — not yet source-verified

CMP polishers planarize wafer surfaces by combining chemical etching with mechanical abrasion, removing excess material and producing a flat, smooth surface for subsequent lithography steps.

How it works

General reference — not yet source-verified

A CMP polisher uses a rotating platen covered with a polishing pad. A wafer is held by a carrier that presses it against the pad with controlled downforce while a chemical slurry is dispensed onto the pad. The combined chemical and mechanical action removes material and planarizes the wafer.

Where it fits in the process flow

General reference — not yet source-verified

CMP is a critical step in semiconductor fabrication, typically performed after deposition of dielectric or metal layers to planarize the topography before photolithography. The process removes excess material and creates a flat surface that ensures accurate pattern transfer.

Upstream processes include chemical vapor deposition (CVD) or physical vapor deposition (PVD); downstream steps involve cleaning and inspection before the next lithography cycle.
