Abstract: Apparatuses and methods for suppressing thermally induced motion of a workpiece. An apparatus includes a workpiece heating system configured to thermally induce motion of a workpiece, and further includes a damping member spaced apart from the workpiece and configured to apply a damping force to dampen the motion of the workpiece. The damping member may be spaced apart from a rest position of the workpiece by a distance sufficiently small that gas pressure between the damping member and the workpiece opposes the motion of the workpiece. The distance is preferably adjustable.

Abstract: A method involves pre-heating a workpiece to an intermediate temperature, heating a surface of the workpiece to a desired temperature greater than the intermediate temperature, and enhancing cooling of the workpiece. Enhancing cooling may involve absorbing radiation thermally emitted by the workpiece. An apparatus includes a first heating source for heating a first surface of a semiconductor wafer, a second heating source for heating a second surface of the semiconductor wafer, and a first cooled window disposed between the first heating source and the semiconductor wafer.

Abstract: Methods and systems for heat-treating a workpiece are disclosed. One method involves increasing a temperature of the workpiece over a first time period to an intermediate temperature, and heating a surface of the workpiece to a desired temperature greater than the intermediate temperature, the heating commencing within less time following the first time period than the first time period. Another method involves pre-heating the workpiece from an initial temperature to an intermediate temperature, and heating a surface of the workpiece to a desired temperature greater than the intermediate temperature by an amount less than or equal to about one-fifth of a difference between the intermediate and initial temperatures. Another method involves irradiating a first side of the workpiece to pre-heat the workpiece to an intermediate temperature, and irradiating a second side of the workpiece to heat the second side to a desired temperature greater than the intermediate temperature.
