  • Publication number: 20170316964
    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.

  • Publication number: 20170271131
    Abstract: Implementations described herein provide apparatus and methods for laser-assisted deposition of films while forming electronic devices. In one implementation, a method for depositing a layer on one or more substrates is provided. The method comprises flowing a deposition precursor gas across a surface of the one or more substrates disposed within a processing volume of a processing chamber, thermally activating the deposition precursor gas to deposit a material layer on the surface of the one or more substrates, dissociating an etch precursor gas in a gas activation cell by exposing the etch precursor gas to photons from an energy source assembly having a wavelength selected for pyrolytic dissociation of the etch precursor gas and introducing the dissociated etch precursor gas into the processing volume to etch at least a portion of the material layer from the surface of the one or more substrates.

  • Publication number: 20170263466
    Abstract: Embodiments disclosed herein generally relate to methods and apparatus for processing of the bottom surface of a substrate to counteract thermal stresses thereon. Correcting strains are applied to the bottom surface of the substrate which compensate for undesirable strains and distortions on the top surface of the substrate. Specifically designed films may be formed on the back side of the substrate by any combination of deposition, implant, thermal treatment, and etching to create strains that compensate for unwanted distortions of the substrate. In some embodiments, localized strains may be introduced by locally altering the hydrogen content of a silicon nitride film or a carbon film, among other techniques. Structures may be formed by printing, lithography, or self-assembly techniques. Treatment of the layers of film is determined by the stress map desired and includes annealing, implanting, melting, or other thermal treatments.

  • Patent number: 9748121
    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.

  • Publication number: 20170072505
    Abstract: The present invention generally describes apparatuses and methods used to perform an annealing process on desired regions of a substrate. In one embodiment, pulses of electromagnetic energy are delivered to a substrate using a flash lamp or laser apparatus. The pulses may be from about 1 nsec to about 10 msec long, and each pulse has less energy than that required to melt the substrate material. The interval between pulses is generally long enough to allow the energy imparted by each pulse to dissipate completely. Thus, each pulse completes a micro-anneal cycle. The pulses may be delivered to the entire substrate at once, or to portions of the substrate at a time. Further embodiments provide an apparatus for powering a radiation assembly, and apparatuses for detecting the effect of pulses on a substrate.
