Abstract
A chemical mechanical polishing apparatus includes a platen to support a polishing pad, an actuator, a carrier head to hold a surface of a substrate against the polishing pad, a motor to generate relative motion between the platen and the carrier head so as to polish an overlying layer on the substrate. The platen has a central section with an upper surface and an annular flexure surrounding or surrounded by the central section and having a top surface with a first edge adjacent to and coplanar with the upper surface and a second edge farther from the central section. The actuator is arranged to bend the annular flexure along an entire circumference of the annular flexure so as to modify a vertical position of the second edge of the annular flexure relative to the central section.
