  • Patent number: 8292697
    Abstract: A carrier structure for supporting a substrate when being processed by passing the carrier through a meniscus formed by upper and lower proximity heads is described. A method of manufacturing the carrier further described. The method includes forming a composite frame having a carbon fiber core, a top sheet, a bottom sheet, a layer of aramid fabric between the top sheet and the core and a second layer of aramid fabric between the bottom sheet and the core. The top sheet and the bottom are each formed from a polymer material. The method further includes forming an opening sized for receiving a substrate and providing a plurality of support pins extending into the opening for supporting the substrate within the opening. The opening is formed slightly larger than the substrate such that a gap exists between the substrate and the opening.

  • Patent number: 8279577
    Abstract: A support for a substrate processing chamber comprises a chuck having a substrate receiving surface, and a base comprising an upper wall comprising a recessed trench having (i) an attachment face at a first depth, and (ii) a fluid channel at a second depth. A lower wall is seated in the recessed trench and attached to the attachment face of the upper wall, to close the fluid channel. A fluid inlet is provided to supply a heat transfer fluid to the fluid channel and a fluid outlet provided to discharge the heat transfer fluid from the fluid channel.

  • Patent number: 7768765
    Abstract: A support for a substrate processing chamber comprises a fluid circulating reservoir comprising a channel having serpentine convolutions. A fluid inlet supplies a heat transfer fluid to the fluid circulating reservoir and a fluid outlet discharges the heat transfer fluid. In one version, the channel is doubled over to turn back upon itself.

  • Patent number: 7221553
    Abstract: A support for a substrate processing chamber has upper and lower walls that are joined by a peripheral sidewall to define a reservoir. A fluid inlet supplies a heat transfer fluid to the reservoir. In one version, a plurality of protrusions extends into the reservoir to perturb the flow of the heat transfer fluid through the reservoir. In another version, the reservoir is an elongated channel having one or more of (i) serpentine convolutions, (ii) integral fins extending into the channel, (iii) a roughened internal surface, or (iv) a changing cross-section. A fluid outlet discharges the heat transfer fluid from the reservoir.
