    摘要: 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.

    摘要: As part of a system for processing a workpiece by applying a controlled heat to the workpiece, a heating arrangement includes an array of spaced apart heating elements for use in a confronting relationship with the workpiece to subject the workpiece to a direct radiation that is produced. A radiation shield includes a plurality of members supported for movement between (i) retracted positions, which allow the direct radiation to reach the workpiece, and (ii) extended positions, in which the plurality of members cooperate in way which serves to at least partially block the direct radiation from reaching the workpiece and to absorb radiation emitted and reflected by the workpiece and thereby achieve greater control of the time-temperature profile than previously obtainable. At least certain ones of the members move between adjacent ones of the heating elements in moving those certain members between the retracted and extended positions. Tubular, curved and plate-like member configurations can be used.

    摘要: A customizable chamber spectral response is described which can be used at least to tailor chamber performance for wafer heating, wafer cooling, temperature measurement, and stray light. In one aspect, a system is described for processing a treatment object having a given emission spectrum at a treatment object temperature which causes the treatment object to produce a treatment object radiated energy. The chamber responds in a first way to the heating arrangement radiated energy and in a second way to the treatment object radiated energy that is incident thereon. The chamber may respond in the first way by reflecting the majority of the heat source radiated energy and in the second way by absorbing the majority of the treatment object radiated energy. Different portions of the chamber may be treated with selectively reflectivity based on design considerations to achieve objectives with respect to a particular chamber performance parameter.
