    Abstract: A substrate support assembly includes a ceramic puck and a thermally conductive base having an upper surface that is bonded to the ceramic puck. The thermally conductive base includes a plurality of thermal zones and a thermally managed material embedded in the thermally conductive base at the upper surface of the thermally conductive base in one or more of the plurality of thermal zones. The thermally managed material has different thermal conductive properties along a first direction and a second direction. The thermally conductive base further includes a plurality of thermal isolators that extend from the upper surface of the thermally conductive base towards a lower surface of the thermally conductive base between two or more of the plurality of thermal zones without contacting the lower surface of the thermally conductive base. Each of the plurality of thermal isolators provides a degree of thermal isolation.

    Abstract: A method and apparatus for performing post-exposure bake operations is described herein. The apparatus includes a plate stack and enables formation of a first high ion density plasma before the ion concentration within the first high ion density plasma is reduced using a diffuser to form a second low ion density plasma. The second low ion density plasma is an electron cloud or a dark plasma. An electric field is formed between a substrate support and the diffuser and through the second low ion density plasma during post-exposure bake of a substrate disposed on the substrate support. The second low ion density plasma electrically couples the substrate support and the diffuser during application of the electric field. The plate stack is equipped with power supplies and insulators to enable the formation or modification of a plasma within three regions of a process chamber.

    Abstract: A method and apparatus for applying an electric field and/or a magnetic field to a photoresist layer without air gap intervention during photolithography processes is provided herein. The method and apparatus include a transfer device and a plurality of modules. The transfer device is configured to rotate a plurality of substrates between each of the modules, wherein one module includes a heating pedestal and another module includes a cooling pedestal. One module is utilized for inserting and removing the substrates from the system. At least the heating module is able to be sealed and filled with a process volume before applying the electric field.

    Abstract: A substrate support assembly includes a ceramic puck and a thermally conductive base having an upper surface that is bonded to a lower surface of the ceramic puck. Trenches are formed in the thermally conductive base approximately concentric around a center of the thermally conductive base. The trenches extend from the upper surface towards a lower surface of the thermally conductive base without contacting the lower surface of the thermally conductive base. The thermally conductive base includes thermal zones. The substrate support assembly further includes a thermally insulating material disposed in the trenches. The thermally insulating material in a trench of the trenches provides a degree of thermal isolation between two of the thermal zones separated by the trench at the upper surface of the thermally conductive base.

    Abstract: The present disclosure generally comprises a heated showerhead assembly that may be used to supply processing gases into a processing chamber. The processing chamber may be an etching chamber. When processing gas is evacuated from the processing chamber, the uniform processing of the substrate may be difficult. As the processing gas is pulled away from the substrate and towards the vacuum pump, the plasma, in the case of etching, may not be uniform across the substrate. Uneven plasma may lead to uneven etching. To prevent uneven etching, the showerhead assembly may be separated into two zones each having independently controllable gas introduction and temperature control. The first zone corresponds to the perimeter of the substrate while the second zone corresponds to the center of the substrate. By independently controlling the temperature and the gas flow through the showerhead zones, etching uniformity of the substrate may be increased.
