Abstract
The present disclosure relates to flow guide structures and heat shield structures, and related methods, for deposition uniformity and process adjustability. In one implementation, an apparatus for substrate processing includes a chamber body that includes a processing volume. The apparatus includes one or more heat sources. The apparatus includes a flow guide structure positioned in the processing volume. The flow guide structure includes one or more first flow dividers that divide the processing volume into a plurality of flow levels, and one or more second flow dividers oriented to intersect the one or more first flow dividers and divide each flow level of the plurality of flow levels into a plurality of flow sections. The flow guide structure includes one or more third flow dividers oriented to intersect the one or more second flow dividers and divide the plurality of flow sections into a plurality of flow zones.
