A device includes a hybrid puck corresponding to an electrostatic chuck. The hybrid puck includes a backing region and a chucking region disposed on the backing region. The backing region includes a first dielectric material to improve thermal performance of the hybrid puck. The chucking region includes a second dielectric material different from the first dielectric material to improve leakage current stability.

Methods and systems for in-situ temperature control are provided. The method includes delivering a temperature-sensing disc into a processing region of a processing chamber without breaking vacuum. The temperature-sensing disc includes one or more cameras configured to perform IR-based imaging. The method further includes measuring a temperature of at least one region of at least one chamber surface in the processing region of the processing chamber by imaging the at least one surface using the temperature-sensing disc. The method further includes comparing the measured temperature to a desired temperature to determine a temperature difference. The method further includes adjusting a temperature of the at least one chamber surface to compensate for the temperature difference.
