ABSTRACT:
An oven is described that can more evenly heat the semiconductor wafer, even though the wafer may warp during heating. The oven may provide relatively uniform heating even though the type and location of warping may be unpredictable for any given wafer. The oven may have a heating surface divided into a plurality of heating zones that may each independently provide a given amount of heat to the wafer. The amount of heat provided by each zone may be determined using signals from sensors that sense the warping of the wafer.
