Abstract:
An immobilization particle for immobilizing a target microorganism or target chemical found in or on a mammal that includes: immobilization molecules capable of attaching to a target microorganism or a target chemical, which immobilization molecules are attached to one or more portions of a substrate structure; wherein the substrate structure is capable of inhibiting contact between tissues of the mammal and target microorganisms or target chemicals attached to immobilization molecules attached to the one or more portions.
Abstract:
An embodiment entails administering an effective amount of a product such as a protease or a source of a protease that destroys or deactivates an immunogen, mimic or antigen specific to a particular autoimmune disease before it encounters the immune system of a patient.
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.
Abstract:
A device for heating a semiconductor wafer comprises a heating element arranged to conduct heat toward the wafer. The heating element can extend along a heating element path. An RTD sensor loop can extend along an RTD sensor path. The RTD sensor path can be positioned along the heating element path to measure a temperature that corresponds to the heating element. The RTD sensor loop can measure an average temperature along the heating element. Portions of the RTD sensor can be interlaced between portions of the heating element. The heating element path can be arranged with interstices between portions of the heating element path, and portions of the RTD sensor path can be positioned within the interstices to interlace the RTD sensor loop with the heating element. The RTD sensor loop can comprise a soft metal that is resistant to oxidation and extends along the RTD sensor path.
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.
Abstract:
A method of clamping/declamping a semiconductor wafer on an electrostatic chuck in ambient air includes disposing the semiconductor wafer at a predetermined distance above a dielectric surface of the electrostatic chuck having one or more electrodes and applying a first voltage greater than a predetermined threshold to the one or more electrodes of the electrostatic chuck for a first time period. The method includes reducing the first voltage to a second voltage substantially equal to a self bias potential of the semiconductor wafer after the first time period. The method includes maintaining the second voltage for a second time period and adjusting the second voltage to a third voltage characterized by a polarity opposite to that of the first voltage and a magnitude smaller than the predetermined threshold. The method includes reducing the third voltage to a fourth voltage substantially equal to the second voltage after a third time period.
Abstract:
A method of performing a thermal process using a bake plate of a track lithography tool. The bake plate includes a plurality of heater zones. The method includes providing a first drive signal to a first electrode in electrical communication with a process surface of the bake plate. The first electrode is associated with a first heater zone of the plurality of heater zones and each of the plurality of heater zones is adapted to receive a control voltage. The method also includes moving a semiconductor substrate toward the process surface of the bake plate, receiving a first response signal from the first electrode, processing the first response signal to determine a first capacitance value associated with a first gap between the first electrode and a first portion of the semiconductor substrate, and providing a measurement signal related to the first capacitance value.
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.
