Abstract
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.
