  • Publication number: 20250104982
    Abstract: An apparatus comprises a vacuum chamber with a processing zone, an RF generator, a sensor, and a controller. The vacuum chamber is configured to receive process gas for a plasma-based process of a substrate. The RF generator provides an RF signal between a first electrode and a second electrode of the vacuum chamber to generate plasma for the plasma-based process. The sensor is configured to sense at least one signal characteristic of the RF signal. The controller is configured to retrieve during the plasma-based process, a plurality of signals from the sensor. The plurality of signals is indicative of the at least one signal characteristic of the RF signal at a corresponding plurality of time instances. The controller determines an endpoint for the plasma-based process based on the plurality of signals from the sensor. The controller terminates the plasma-based process based on the endpoint.

  • Publication number: 20250054760
    Abstract: Examples are disclosed that relate to depositing a carbon mask to thicken a partially etched mask. One example provides a method comprising forming a mask layer on a substrate, and etching the substrate to partially form one or more etched features, the etching of the substrate also causing etching of the mask layer. The method further comprises, after etching a portion of the one or more etched features but before completing etching of the one or more etched features, depositing, by plasma-enhanced chemical vapor deposition (PECVD), a carbon mask over the mask layer.

  • Publication number: 20240420927
    Abstract: One example provides a fabrication tool comprising a chamber, a pedestal electrode and a showerhead electrode arranged in the chamber, one or more gas inlets into the chamber, a vacuum pump system, a radiofrequency (RF) power source configured to form an RF plasma between the pedestal electrode and the showerhead electrode, and a controller comprising a processor and memory. The memory comprises instructions executable by the processor to operate the flow control hardware to introduce a hydrogen-containing reducing agent and a hydrocarbon gas into the chamber, and to operate the RF power source to form a plasma between the pedestal electrode and the showerhead electrode to fully deposit a carbon plug in a recess of a workpiece positioned on a pedestal within the chamber in a single plasma deposition cycle with no intermediate carbon removal process.

  • Publication number: 20230323532
    Abstract: In some examples, a rib cover is provided for a multi-station processing module having a rib disposed between adjacent processing chambers. An example rib cover comprises a first portion for supporting the rib cover on the rib, a first side shield to cover a first wall of the rib when the rib cover is fitted thereto, and at least one spacer to hold an inner surface of the rib cover away from the covered rib.

  • Patent number: 9394414
    Abstract: The present disclosure relates to films such as membranes and coatings and to coated articles. The films comprise a combination of at least one elastomeric styrenic block copolymer which is optionally functionalized with functional groups different from sulfonic acid or sulfonate ester functional groups, and at least one sulfonated block copolymer. Films comprising the optionally functionalized block copolymer(s) and the additional sulfonated block copolymer(s) are elastic and are moisture-vapor permeable, and thus useful as coatings in breathable clothing and footwear, industrial workwear including cleanroom coveralls, in medical applications such as wound dressings and protective clothing, for bed sheets and mattress or seat covers, and other non-apparel applications.

  • Publication number: 20140353449
    Abstract: Generally disclosed are apparatus and related methods for blunting sharp corners or otherwise reducing the force of an impact with sharp corners. In one embodiment, the apparatus may generally be in the form of a creature with at least a torso and four appendages defined internally by a skeleton of foam members having a bendable metal core. In use, the appendages may be bent around corners so that the torso of the creature removably, yet securely, resides over the corner whereby the corners are blunted or otherwise the force of impacts with the corner are reduced (e.g., the foam and other components of the apparatus may act as a shock absorber). In a preferred embodiment, a stomach portion of the torso features a non-slip padding that may receive the corner to be blunted to further secure the apparatus over the targeted corner.

  • Patent number: 8821986
    Abstract: Provided are processes for the low temperature deposition of silicon-containing films using activated SiH-containing precursors. The SiH-containing precursors may have reactive functionality such as halogen or cyano moieties. Described are processes in which halogenated or cyanated silanes are used to deposit SiN films. Plasma processing conditions can be used to adjust the carbon, hydrogen and/or nitrogen content of the films.

  • Publication number: 20140069624
    Abstract: An article made up of a substrate which has a polymer coating applied to at least one of its surfaces, wherein the polymer coating forms an interrupted pattern such that at least 10% to 80% of the substrate surface remains uncoated, and wherein the polymer coating comprises a moisture permeable polymer.

  • Publication number: 20140038427
    Abstract: Provided are processes for the low temperature deposition of silicon-containing films using carbosilane precursors containing a carbon atom bridging at least two silicon atoms. Certain methods comprise providing a substrate; in a PECVD process, exposing the substrate surface to a carbosilane precursor containing at least one carbon atom bridging at least two silicon atoms; exposing the carbosilane precursor to a low-powered energy sourcedirect plasma to provide a carbosilane at the substrate surface; and densifying the carbosilanestripping away at least some of the hydrogen atoms to provide a film comprising SiC. The SiC film may be exposed to the carbosilane surface to a nitrogen source to provide a film comprising SiCN.

  • Patent number: 8440571
    Abstract: Methods for deposition of silicon carbide films on a substrate surface are provided. The methods include the use of vapor phase carbosilane precursors and may employ plasma enhanced atomic layer deposition processes. The methods may be carried out at temperatures less than 600° C., for example between about 23° C. and about 200° C. or at about 100° C. This silicon carbide layer may then be densified to remove hydrogen content. Additionally, the silicon carbide layer may be exposed to a nitrogen source to provide reactive N—H groups, which can then be used to continue film deposition using other methods. Plasma processing conditions can be used to adjust the carbon, hydrogen and/or nitrogen content of the films.
