摘要:
A direct (DC) voltage is applied to an electrode at a voltage value to clamp a workpiece to an electrostatic chuck in a processing chamber. The electrode is embedded into the electrostatic chuck. An electrostatic chuck current through the electrode at the DC voltage is measured. A DC self bias induced on the workpiece by a plasma is determined based on the electrostatic chuck current and the applied voltage.

We disclose a method of using taggants to assess how and to what extent a drug in a drug composition that a user has consumed has decayed in response to storage conditions and time. The taggants may decay in response to environmental conditions which cause different drugs to lose their efficacy. These environmental conditions may include light, temperature, oxidation, and age. The taggants may be detected in biological samples, including urine and feces. By identifying the taggants, the drug composition and other information relating to the drug may be identified. Additionally, quantification of the different taggants may be used to determine whether the drug in the drug composition has been exposed to environmental conditions which may reduce its efficacy.

摘要:
Apparatus for controlling the thermal uniformity of a substrate. In some embodiments, the thermal uniformity of the substrate is controlled to be more uniform. In some embodiments, the thermal uniformity of the substrate is controlled to be non-uniform in a desired pattern. In some embodiments, an apparatus for controlling thermal uniformity of a substrate includes a substrate support having a support surface to support a substrate thereon. A plurality of flow paths having a substantially equivalent fluid conductance are disposed within the substrate support to flow a heat transfer fluid beneath the support surface.

Aspects of the present disclosure describe an attachment device for mounting a module to a substrate comprises a module leg with two ends and a module foot. One end of the module leg is configured to be attached to a bottom surface of the module and the other end of the module leg is configured to be attached to the module foot. At least a portion of the module foot is configured to be attached to the substrate. Also a portion of a surface area of the module foot is configured to be exposed outside of an area covered by the module. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
摘要:
Methods and apparatus for controlling the temperature of a substrate during processing are provided herein. In some embodiments, an apparatus for retaining and controlling substrate temperature may include a puck of dielectric material; an electrode disposed in the puck proximate a surface of the puck upon which a substrate is to be retained; and a plurality of heater elements disposed in the puck and arranged in concentric rings to provide independent temperature control zones.
摘要:
A plasma processing chamber has a lower liner with an integrated flow equalizer. In an etching process, the processing gases may be unevenly drawn from the processing chamber which may cause an uneven etching of the substrate. The integrated flow equalizer is configured to equalize the flow of the processing gases evacuated from the chamber via the lower liner.
摘要:
A method is provided for processing a workpiece in a plasma reactor chamber. The method includes coupling, to a plasma in the chamber, power of an RF frequency via a ceiling electrode and coupling, to the plasma, power of at least approximately the same RF frequency via a workpiece support electrode. The method also includes providing an edge ground return path. The method further includes adjusting the proportion between (a) current flow between said electrodes and (b) current flow to the edge ground return path from said electrodes, to control plasma ion density distribution uniformity over the workpiece.
摘要:
A flow equalizer plate is provided for use in a substrate process chamber. The flow equalizer plate has an annular shape with a flow obstructing inner region, and a perforated outer region that permits the passage of a processing gas, but retains specific elements in the processing gas, such as active radicals or ions. The inner and outer regions have varying radial widths so as to balance a flow of processing gas over a surface of a substrate. In certain embodiments, the flow equalizer plate may be utilized to correct chamber flow asymmetries due to a lateral offset of an exhaust port relative to a center line of a substrate support between the process volume and the exhaust port.
