TRÄGERPLATTE MIT LOKALER DRUCKSTEUERUNG FÜR EINE CHEMISCH-MECHANISCHE POLIERVORRICHTUNG |
摘要 |
A carrier head for a chemical mechanical polishing apparatus includes a flexible membrane, the lower surface of which provides a substrate-receiving surface. The carrier head may include a projection which contacts an upper surface of the flexible membrane to apply an increased load to a potentially underpolished region of a substrate. Fluid jets may be used for the same purpose. |
