Embodiments described herein generally relate to plasma assisted or plasma enhanced processing chambers. More specifically, embodiments herein relate to electrostatic chucking (ESC) substrate supports configured to provide pulsed DC voltage, and methods of applying a pulsed DC voltage, to a substrate during plasma assisted or plasma enhanced semiconductor manufacturing processes.

Substrate support with electrically floating power supply

Electrostatic chucks (ESCs) with RF and temperature uniformity are described. For example, an ESC includes a top dielectric layer. An upper metal portion is disposed below the top dielectric layer. A second dielectric layer is disposed above a plurality of pixilated resistive heaters and surrounded in part by the upper metal portion. A third dielectric layer is disposed below the second dielectric layer, with a boundary between the third dielectric layer and the second dielectric layer. A plurality of vias is disposed in the third dielectric layer. A bus power bar distribution layer is disposed below and coupled to the plurality of vias. A fourth dielectric layer is disposed below the bus bar power distribution layer, with a boundary between the fourth dielectric layer and the third dielectric layer. A metal base is disposed below the fourth dielectric layer. The metal base includes a plurality of high power heater elements housed therein.
