A susceptor support shaft supports a susceptor thereon, which in turn, supports a substrate during processing. The susceptor support shaft reduces variations in temperature measurement of the susceptor and/or substrate by providing a consistent path for a pyrometer focal beam directed towards the susceptor and/or substrate, even when the susceptor support shaft is rotated. The susceptor support shafts also have a relatively low thermal mass which increases the ramp up and ramp down rates of a process chamber. In some embodiments, a custom made refractive element can be removably placed on the top of the solid disc to redistribute secondary heat distributions across the susceptor and/or substrate for optimum thickness uniformity of epitaxy process.

  • Publication number: 20130270250
    Abstract: A method of operating a heating plate for a substrate support assembly used to support a semiconductor substrate in a semiconductor processing apparatus, wherein the heating plate comprises power supply lines and power return lines and respective heater zone connected between every pair of power supply line and power return line. The method reduces maximum currents carried by the power supply lines and power return lines by temporally spreading current pulses for powering the heater zones.

  • Patent number: 8511651
    Abstract: A heater unit is adapted to determine if a humidification chamber thermally coupled to a hot plate of the heater unit is effectively dry based on determining a thermal response of a hot plate of the heater unit. Also, the activation period during which the hot plate is being heated is adjusted toward an optimum period by adjusting the energization or power level to the heater element thereof in relation to the duration of a prior activation period. Further, the air flow rate of gas through the humidification chamber may be estimated based on a temperature of the hot plate determined in predetermined relationship to the beginning of an activation period.

  • Publication number: 20130168379
    Abstract: The invention relates to a combination of an electrical heating element and a heat dissipater to be heated thereby; the heating element comprises a substrate, an insulating layer located on the substrate and a thick film conductor located on the insulating layer, wherein the second side of the metallic substrate is in contact with the heat dissipater, comprising a layer of metallic material on its face towards the heater and wherein the substrate is brazed to the heat dissipater and the surface of the heating element over which the thick film conductor extends, is substantially equal to the surface of the heat dissipater. The brazing leads to a permanent contact between the heating element and the heat dissipater, so that the possible tendency for warping as caused by the heating and cooling cycles will be withstood.

  • Patent number: 8454357
    Abstract: The hotplate for a workpiece comprises a heatable plate which on a first side comprises a support surface for the workpiece, several lifting elements for the lifting of the workpiece relative to the support surface, wherein each lifting element is moveably arranged in such a manner that the respective lifting element can be retracted with respect to the support surface and/or extended with respect to the support surface and means for heating the plate. The means for heating comprise at least one heating channel which extends on a second side of the plate located opposite the support surface and is filled with a heating fluid. The heating fluid is in contact with the plate. The lifting elements are loaded with the heating fluid in such a manner that the lifting elements are extendable through a predetermined change of the hydrostatic pressure of the heating fluid.
