A process chamber is provided including a top, a bottom, and a sidewall coupled together to define a volume. A substrate support is disposed in the volume. The process chamber further includes one or more lampheads facing the substrate support, each lamphead comprising an arrangement of lamps disposed along a plane. The arrangement of lamps is defined by a center and a plurality of concentric ring-shaped zones. Each ring-shaped zone is defined by an inner edge and an outer edge and each ring-shaped zone includes three or more alignments of one or more lamps. Each alignment of one or more lamps has a first end extending linearly to a second end that are separated by at least 10 degrees around the center. The first end and the second end are both located within one ring-shaped zone. Each alignment located within a same ring-shaped zone is equidistant to the center. |
