Apparatuses and methods for supporting a workpiece such as a semiconductor wafer. A support system is configured to support the workpiece while allowing thermally-induced motion of the workpiece, which may include thermal bowing or thermal bending. The system may include a support member having a moveable engagement portion engageable with the workpiece, the engagement portion being moveable to allow the thermally-induced motion of the workpiece while supporting the workpiece. The moveable engagement portion may include a plurality of moveable engagement portions of a plurality of respective support members, which may be resiliently engageable with the workpiece. The support members may include flexible support members each having an unconstrained portion and a constrained portion, and the moveable engagement portions may include the unconstrained portions. Alternatively, the support members may be rigid and the system may include a plurality of force applicators such as springs in communication with the support members.

Methods and systems for supporting a workpiece and for heat-treating the workpiece

An apparatus for generating electromagnetic radiation includes an envelope, a vortex generator configured to generate a vortexing flow of liquid along an inside surface of the envelope, first and second electrodes within the envelope configured to generate a plasma arc therebetween, and an insulative housing associated surrounding at least a portion of an electrical connection to one of the electrodes. The apparatus further includes a shielding system configured to block electromagnetic radiation emitted by the arc to prevent the electromagnetic radiation from striking all inner surfaces of the insulative housing. The apparatus further includes a cooling system configured to cool the shielding system.

Apparatus and methods for generating electromagnetic radiation

An apparatus for supporting a workpiece during heat-treating includes a support plate having a non-planar upper surface, and a support system. The support system is configured to support the workpiece above the support plate during heat-treating of the workpiece, such that a lower surface of an initial shape of the workpiece is supported at a non-uniform spacing above the non-planar upper surface of the support plate, said non-uniform spacing including an edge gap beneath an outer perimeter of the workpiece, and a central gap at a central axis of the workpiece.

Systems and methods for supporting a workpiece during heat-treating

An apparatus for supporting a semiconductor workpiece includes a heating system configured to cause thermally-induced motion of the semiconductor workpiece by heating a surface of the workpiece relative to a bulk of the workpiece. The thermally-induced motion includes vertical motion of an outer edge region of the workpiece and a center of the workpiece relative to each other. The apparatus further includes a support system configured to allow the thermally-induced motion including the vertical motion of the outer edge region of the workpiece and the center of the workpiece relative to each other while supporting the workpiece.

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.
