    Abstract: A body of an electrostatic chuck comprises mesas disposed on a polished surface of the body. Each of the mesas comprises an adhesion layer disposed on the polished surface of the body, a transition layer disposed over the adhesion layer, and a coating layer disposed over the transition layer. The coating layer has a hardness of at least 14 GPa. The body further comprises a sidewall coating disposed over a sidewall of the body. A method for preparing the body comprises polishing the surface of the body and cleaning the polished surface. The method further comprises depositing the mesas by depositing the adhesion layer on the body, the transition layer over the adhesion layer, and the coating layer over the transition layer. Further, the method includes, polishing the mesas.

    Abstract: The present disclosure relates to a flexible support to aid in a measurement of flatness of a susceptor. The flexible support has a first support block having a substantially flat upper surface and a lower surface having a first aperture formed therein. The flexible support further has a second support block having a substantially flat lower surface and an upper surface having a second aperture formed therein. The flexible support further has a support pin configured to be receivable in the first aperture and the second aperture, the support pin configured to retain the first support block and the second support block in a spaced apart relation while allowing restricted motion of the first support block relative to the second support block via deformation of the support pin. The flexible support further has a guide disposed between the first support block and the second support block, the guide configured to allow the first support block and the second support block to move axially relative to the guide.

    Abstract: Methods and apparatus reduce chucking abnormalities for electrostatic chucks by ensuring proper planarizing of ceramic surfaces of the electrostatic chuck. In some embodiments, a method for planarizing an upper ceramic surface of an electrostatic chuck assembly may comprise placing the electrostatic chuck assembly in a first planarizing apparatus, altering an upper ceramic surface of the electrostatic chuck assembly, and halting the altering of the upper ceramic surface of the electrostatic chuck assembly when an Sa parameter is less than approximately 0.1 microns, an Sdr parameter is less than approximately 2.5 percent, an Sz parameter is less than approximately 10 microns for any given area of approximately 10 mm2 of the upper ceramic surface, or a pit-porosity depth parameter of greater than 1 micron is less than approximately 0.1 percent of area of the upper ceramic surface.
