Abstract:
1. A method of thermally treating an object, the method comprising: providing an object in a thermal processing chamber; positioning a thermal transfer plate in close thermal communication with the object, the thermal transfer plate having a thermal mass no greater than about three times the thermal mass of the object; pre-heating the object; and heating the object by directing at least one pulse of energy toward the object for a duration of less than 1 s such that the average temperature of the semiconductor wafer increases by a temperature difference ΔT to a peak temperature; wherein the thermal transfer plate is configured and positioned such that the cooling rate from the object is enhanced such that the average temperature of the object is brought down from the peak temperature by at least 50% of the value of ΔT within 1.0 s.
