  • Patent number: 9863043
    Abstract: Embodiments described herein generally relate to apparatus for processing substrates. The apparatus generally include a process chamber including a lamp housing containing lamps positioned adjacent to an optically transparent window. Lamps within the lamp housing provide radiant energy to a substrate positioned on the substrate support. Temperature control of the optically transparent window is facilitated using cooling channels within the lamp housing. The lamp housing is thermally coupled to the optically transparent window using compliant conductors. The compliant conductors maintain a uniform conduction length irrespective of machining tolerances of the optically transparent window and the lamp housing. The uniform conduction length promotes accurate temperature control. Because the length of the compliant conductors is uniform irrespective of machining tolerances of chamber components, the conduction length is the same for different process chambers.

  • Patent number: 9863038
    Abstract: Disclosed are method and apparatus for treating a substrate. The apparatus is a dual-function process chamber that may perform both a material process and a thermal process on a substrate. The chamber has an annular radiant source disposed between a processing location and a transportation location of the chamber. Lift pins have length sufficient to maintain the substrate at the processing location while the substrate support is lowered below the radiant source plane to afford radiant heating of the substrate. A method of processing a substrate having apertures formed in a first surface thereof includes depositing material on the first surface in the apertures and reflowing the material by heating a second surface of the substrate opposite the first surface. A second material can then be deposited, filling the apertures partly or completely. Alternately, a cyclical deposition/reflow process may be performed.

  • Publication number: 20170338135
    Abstract: Embodiments described herein generally relate to apparatus for processing substrates. The apparatus generally include a process chamber having a substrate support therein. A plurality of lamps are positioned to provide radiant energy through an optically transparent window to a substrate positioned on the substrate support. The plurality of lamps are positioned in a lamp housing. A cooling channel is formed in the lamp housing. A surface of the lamp housing is spaced a distance from the optically transparent window to form a gap therebetween. The gap functions as a fluid channel and is adapted to contain a fluid therein to facilitate cooling of the optically transparent window. Turbulence inducing features, such as openings, formed in the surface of the lamp housing induce a turbulent flow of the cooling fluid, thus improving heat transfer between the optically transparent window and the lamp housing.
