Definition
A CMP polisher presses a rotating wafer against a conditioned pad while delivering slurry, controlling pressure zones, relative velocity, temperature, endpoint, and post-polish handling to remove selected films with target planarity and defectivity.
Process position
Inputs
- Topographic wafer
- CMP slurry
- Conditioned pad
- Removal and endpoint recipe
Outputs
- Planarized wafer
- Removal and endpoint data
- Wafer for post-CMP clean
How it works
- 01Condition pad and prime slurry
- 02Load and align wafer
- 03Polish under zoned pressure
- 04Detect endpoint or timed removal
- 05Rinse and transfer to clean
Role in the production flow
CMP creates a usable surface for subsequent layers by jointly controlling chemical reaction and mechanical removal. Pattern density, materials, pad state, slurry age, and carrier-head behavior all shape local and wafer-scale planarity.
A wafer-polishing system that combines controlled mechanical contact and slurry chemistry to remove topography and expose a planar process surface.
Boundary: The cited manufacturers document the equipment category and its intended uses; this record does not independently validate vendor performance claims or rank products.
Qualification and production boundaries
A qualified process must bind tool, pad, slurry, conditioner, retaining ring, pressure recipe, endpoint method, incoming pattern density, removal target, defect limits, post-clean, and consumable lifetime.
A qualified process must bind tool, pad, slurry, conditioner, retaining ring, pressure recipe, endpoint method, incoming pattern density, removal target, defect limits, post-clean, and consumable lifetime.
Boundary: Actual acceptance limits, recipes, throughput, availability, and ownership economics are product-, process-, site-, and contract-specific.
