Abstract:
Embodiments of the present disclosure generally relate to apparatus and methods for semiconductor processing, more particularly, to a thermal process chamber. The thermal process chamber includes a substrate support, a first plurality of heating elements disposed over or below the substrate support, and a spot heating module disposed over the substrate support. The spot heating module is utilized to provide local heating of cold regions on a substrate disposed on the substrate support during processing. Localized heating of the substrate improves temperature profile, which in turn improves deposition uniformity.
