Abstract:
1. A reactor for heat treatment of a flat substrate, comprising: a heated body, having a substantially flat surface facing a flat substrate during processing; a substrate handling mechanism configured to place the flat substrate to be processed parallel to and in close proximity to the substantially flat surface of the heated body, and configured to remove said substrate in a removal direction from the heated body after processing; and a plurality of heating elements associated with the heated body, the heating elements being arranged to define heating zones and are connected to a controller configured to control the heating elements individually, wherein the controller and heating zones are configured to provide for a non-uniform temperature laterally across flat surface of the heated body, wherein the non-uniform temperature is selected to impose a non-uniform temperature on the substrate during processing to compensate for a non-uniform temperature distribution during removal of the substrate from the reactor.
