What it is
How it works
General reference — not yet source-verifiedA CMP machine removes material by bringing a workpiece into contact with a rotating abrasive or polishing surface while a process fluid is used to support controlled surface removal and planarization.
A grinder and polisher class machine uses mechanical motion and consumable surfaces to change flatness, thickness, and surface finish on a substrate.
Where it fits in the process flow
General reference — not yet source-verifiedCMP sits in the late surface-preparation part of semiconductor processing, where the goal is to improve planarity before later patterning or integration steps.
A grinder and polisher can also fit into back-end substrate preparation, where mechanical finishing prepares material for subsequent inspection, bonding, thinning, or finishing operations.
