APPARATUS AND METHODS FOR HEATING TUNABILITY IN PROCESSING CHAMBERS

Embodiments herein are generally directed to electronic device manufacturing and, more particularly, to systems and methods for lamp heating in thermal processing chambers. In an embodiment, an adjustable reflector includes a plurality of reflector elements. Each of the plurality of elements as a first surface, a second surface, and a plurality of sidewalls. The first surface is a reflective surface and is configured to face a lamp. The adjustable reflector includes one or more actuation mechanisms coupled to the plurality of elements. A method of thermally processing a substrate includes measuring a thermal intensity of a thermal profile of an area of a substrate under or over a lamp and the adjustable reflector, and in response to the thermal intensity being outside of desired parameters, adjusting the reflector profile of the reflector assembly along a centerline path.
