Abstract: A system includes a camera mounted external to and adjacent to a window of a processing chamber configured to process semiconductor substrates. The window allows the camera to view a component in the processing chamber. The camera is configured to generate a video signal indicative of a status of the component during a process being performed in the processing chamber. The system further includes a controller coupled to the processing chamber. The controller is configured to control the camera, process the video signal from the camera, determine the status of the component based on the processing of the video signal, and determine whether to terminate the process based on the status of the component.

Abstract: A substrate handling robot includes an arm section and a wrist portion connected to the arm section.

Abstract: Window units, for example insulating glass units (IGU's), that have at least two panes, each pane having an electrochromic device thereon, are described. Two optical state devices on each pane of a dual-pane window unit provide window units having four optical states. Window units described allow the end user a greater choice of how much light is transmitted through the electrochromic window. Also, by using two or more window panes, each with its own electrochromic device, registered in a window unit, visual defects in any of the individual devices are negated by virtue of the extremely small likelihood that any of the visual defects will align perfectly and thus be observable to the user.

Abstract: The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

Abstract: Methods are described for removing a material from a substrate by dissolving an etchant into a solvent to form a solution; and exposing the substrate to the solution so that the etchant in the solution removes material from the substrate; wherein during the exposure the solution is maintained in a supercritical or near-supercritical phase. The described methods can include additional steps, such as exposing a precursor of the material to a reagent to form the material, and depositing a second material onto the substrate after removing the material from the substrate.

Abstract: This invention relates to subterranean treatment operations. More particularly, this invention provides methods that may be useful in providing void-free barriers between a subterranean formation and a portion of a well bore. A nonlimiting example of a method is a method of degrading a filter cake in a subterranean formation.

Abstract: Methods are provided for removing filter cake containing a bridging agent soluble in a carboxylic acid salt from a formation fluids producing zone penetrated by a well bore. The methods basically comprise the steps of introducing in an aqueous carrier liquid a carboxylic acid ester and a base for slowly catalyzing the hydrolysis of the ester and forming a carboxylic acid salt therewith into the producing zone, and allowing the base to catalyze the hydrolysis of the carboxylic acid ester to form the carboxylic acid salt so that the carboxylic acid salt dissolves the bridging agent and the filter cake is removed.

Abstract: Improved methods and compositions for degrading filter cake deposited in a subterranean formation are provided. These methods and compositions utilize particulates coated with acid-releasing degradable material wherein the released acid is used to degrade a filter cake.
