An integrated system for baking and chilling wafers includes a heater for heating a wafer to an elevated temperature, a chiller for cooling the wafer, and a shuttle operatively connected to the heater and the chiller for transferring the wafer between the heater and the chiller. The chiller further includes a low thermal mass wafer support for providing support to a bottom surface of a wafer and a chill plate coupled to the low thermal mass wafer support for cooling the wafer. The low thermal mass wafer support has a higher thermal conductivity in the plane parallel to the bottom surface of the wafer than in the direction perpendicular to the bottom surface of the wafer. The low thermal mass wafer support can further include a plurality of proximity pins for supporting the wafer. |
