APPARATUS FOR CONTROLLING TEMPERATURE UNIFORMITY OF A SUBSTRATE

摘要

Apparatus for controlling thermal uniformity of a substrate is provided herein. In some embodiments, the thermal uniformity of the substrate may be controlled to be more uniform. In some embodiments, the thermal uniformity of the substrate may be controlled to be non-uniform in a desired pattern. In some embodiments, an apparatus for controlling thermal uniformity of a substrate may include a substrate support having a support surface to support a substrate thereon; and a plurality of flow paths having a substantially equivalent fluid conductance disposed within the substrate support to flow a heat transfer fluid beneath the support surface.
