发明名称 A CARRIER HEAD WITH A RETAINING RING FOR A CHEMICAL MECHANICAL POLISHING SYSTEM
摘要 <p>A carrier head for chemical mechanical polishing with a retaining ring having an inclined inner surface. The force of the edge of the substrate against the inclined surface causes a reactive force having a vertical component on the edge of the substrate. This vertical force can reduce the edge effect.</p>
