Abstract:
An apparatus for thermally processing a microelectronic workpiece, comprising:a workpiece support positioned to engage and support the microelectronic workpiece; a heat source having a solid engaging surface positioned to engage a surface of the microelectronic workpiece, the heat source having a plurality of vacuum aperture portions coupleable to a vacuum source, with the solid engaging surface being generally continuous between the vacuum aperture portions, the heat source further having a heat generator attached directly to and/or integral with the heat source, at least one of the heat source and the workpiece support being movable relative to the other between a first position with the microelectronic workpiece contacting the engaging surface of the heat source and a second position with the microelectronic workpiece spaced apart from the engaging surface, the heat source being sized to transfer heat to the microelectronic workpiece at least sufficient to thermally process a selected material of the microelectronic workpiece when the microelectronic workpiece is engaged with the heat source in the first position; and first and second heat sinks with the second heat sink spaced apart from the heat source and coupled to a supply of cooling fluid, the second heat sink further having an engaging surface with vacuum apertures coupled to a vacuum source and the first heat sink positioned between the second heat sink and the heat source, the first heat sink being movable relative to the second heat sink between a first position and a second position, the first heat sink being engaged with the engaging surface of the second heat sink to cover the vacuum apertures and cool the first heat sink when the first heat sink is in the first position, the first heat sink being engaged with the heat source to cool the heat source and the microelectronic workpiece when the microelectronic workpiece is engaged with the heat source and the first heat sink is in the second position.
