Abstract

Embodiments of the present disclosure provide an electrostatic chuck including a ring surrounding a top surface of the electrostatic chuck and a mesa extending along a diameter of the top surface of the electrostatic chuck such that the mesa contacts the ring on opposed ends thereof. The mesa is a single continuous feature. The mesa contacts a bottom surface of a substrate placed over the electrostatic chuck. The electrostatic chuck includes a first electrode and a second electrode. When a voltage is applied to the electrostatic chuck, an electric field is present between the first electrode and the second electrode. The mesa prevents the electric field from creating hatch marks on the top surface of the electrostatic chuck. The mesa is vertically offset from the first electrode and the second electrode or is vertically aligned with a gap defined between the first electrode and the second electrode.
