Abstract

A system and apparatus for thermal treatment of a substrate with improved thermal uniformity is provided. In some embodiments, the system includes a heating element, a substrate-retaining element operable to retain a substrate, and a reflective structure operable to direct thermal energy of the heating element towards the substrate retained in the substrate-retaining element. The reflective structure includes a textured portion wherein a texture of the textured portion is configured to direct the thermal energy towards the retained substrate. In some such embodiments, the texture includes a roughened irregular surface configured to direct the thermal energy towards the retained substrate. In some such embodiments, the texture includes a plurality of circumferential ridge structures configured to direct the thermal energy towards the retained substrate.
