Summary:A method that is performed for heat treating a semiconductor wafer in a process chamber, as an intermediate part of an overall multi-step technique for processing the wafer, includes applying an energy transfer layer to at least a portion of the wafer, and exposing the wafer to an energy source in the process chamber in a way which subjects the wafer to a thermal profile such that the energy transfer layer influences at least one part of the thermal profile. The thermal profile has at least a first elevated temperature event. The method further includes, in time relation to the thermal profile, removing the energy transfer layer in the process chamber at least sufficiently for subjecting the wafer to a subsequent step. An associated intermediate condition of the wafer is described.
