    Abstract: A ceramic layer is attached to a top surface of a base plate using a bond layer. The ceramic layer has a top surface configured to support a substrate. At least one clamp electrode is positioned within an upper region of the ceramic layer. A primary radiofrequency (RF) power delivery electrode is positioned within the ceramic layer at a location vertically below the at least one clamp electrode such that a region of the ceramic layer between the primary RF power delivery electrode and the at least one clamp electrode is substantially free of other electrically conductive material. A plurality of RF power delivery connection modules is distributed in a substantially uniform manner about a perimeter of the ceramic layer. Each of the RF power delivery connection modules is configured to form an electrical connection from the base plate to the primary RF power delivery electrode at its respective location.

    Abstract: A substrate support for control of a temperature of a semiconductor substrate supported thereon during plasma processing of the semiconductor substrate includes a temperature-controlled base having a top surface, a metal plate, and a film heater. The film heater is a thin and flexible polyimide heater film with a plurality of independently controlled resistive heating elements thermally coupled to an underside of the metal plate. The film heater is electrically insulated from the metal plate. A first layer of adhesive bonds the metal plate and the film heater to the top surface of the temperature-controlled base. A layer of dielectric material is bonded to a top surface of the metal plate with a second layer of adhesive. The layer of dielectric material forms an electrostatic clamping mechanism for supporting the semiconductor substrate.

    Abstract: An apparatus for control of a temperature of a substrate has a temperature-controlled base, a heater, a metal plate, a layer of dielectric material. The heater is thermally coupled to an underside of the metal plate while being electrically insulated from the metal plate. A first layer of adhesive material bonds the metal plate and the heater to the top surface of the temperature controlled base. This adhesive layer is mechanically flexible, and possesses physical properties designed to balance the thermal energy of the heaters and an external process to provide a desired temperature pattern on the surface of the apparatus. A second layer of adhesive material bonds the layer of dielectric material to a top surface of the metal plate. This second adhesive layer possesses physical properties designed to transfer the desired temperature pattern to the surface of the apparatus. The layer of dielectric material forms an electrostatic clamping mechanism and supports the substrate.
