发明名称 Electrostatic chuck assembly
摘要 Embodiments of electrostatic chucks for substrate processing are provided herein. In some embodiments, an electrostatic chuck may include a puck for supporting a substrate, the puck formed from a dielectric material and having a chucking electrode disposed within the puck proximate a support surface of the puck to electrostatically retain the substrate when disposed on the puck; a base having a ring extending from the base to support the puck; and a spacer disposed between the base and the puck to support the puck above the base such that a gap is formed between the puck and the base, wherein the spacer supports the puck proximate a peripheral edge of the puck.

主权项 1. An electrostatic chuck, comprising: a puck to support a substrate, the puck formed from a dielectric material and having a chucking electrode disposed within the puck proximate a support surface of the puck to electrostatically retain the substrate when disposed on the puck; a base having a ring extending from the base to support the puck; and a spacer supported atop the ring of the base and disposed between the base and the puck to support the puck above the base such that a gap is formed between the puck and the base, wherein the spacer supports the puck proximate a peripheral edge of the puck.
