A CARRIER HEAD WITH A RETAINING RING FOR A CHEMICAL MECHANICAL POLISHING SYSTEM |
摘要 |
<p>A carrier head (140) for chemical mechanical polishing with a retaining ring (108) having an inclined inner surface (150). The force of the edge of the substrate against the inclined surface (150) causes a reactive force having a vertical component on the edge of the substrate (10). This vertical force can reduce the edge effect.</p> |
