  • Patent number: 12009218
    Abstract: Described herein is a method for etching a sample. The method includes performing a plasma etch pulse. The plasma etch pulse is performed by directing a gas flow comprising silicon tetrachloride (SiCl4) and a diluent towards the sample. While directing the gas flow, a bias power is applied to achieve a bias state for a first time period. Then, a source power is applied to achieve a source state for a second time period, and then no bias power and no source power is applied to achieve a recovery state for a third time period. The plasma etch pulse is repeated until a target amount of the sample is etched.

  • Publication number: 20230104696
    Abstract: In order to shorten the operation time for a registration operator to make a designation to register a subregion where a person or thing to be registered appears in a captured image, this information registration device is provided with a line-of-sight detection unit, an extraction unit and a registration unit. The line-of-sight detection unit detects the line of sight of the registration operator who is looking at the captured image which is shown on a display device. If the registration operator's detected line of sight has not moved for an attention time configured in advance, the extraction unit extracts an image of the person or object appearing in the subregion of the captured image where the registration operator's line of sight is directed. The registration unit registers the extracted image in a predetermined storage device.

  • Publication number: 20220313707
    Abstract: The present disclosure discloses use of a combination of an HIP-1? inhibitor and/or an AR inhibitor in inhibiting an .inflammatory cytokine storm,. treating or preventing viral pneumonia. The present disclosure finds that inhibitors HIF-1 a and AR prevent the transcription of inflammatory cytokine storm-related genes (IL6, MMP2, MMP13, ADAMTS4, ELN, VCAN. COL3A1 and VEGFA) in fibroblasts under low-oxygen environment by effectively inhibiting the interaction between HIF-1? and AR to reduce the expression quantity of the related genes, thereby influencing the activation of lung fibroblasts. Inhibition of activation of lung fibroblasts enables patients with acute respiratory distress syndrome (ARDS) due to severe respiratory tract infection to maintain the lung functions and improve clinical efficacy.

  • Patent number: 9589853
    Abstract: A method of planarizing an upper surface of a semiconductor substrate in a plasma etch chamber comprises supporting the substrate on a support surface of a substrate support assembly that includes an array of independently controlled thermal control elements therein which are operable to control the spatial and temporal temperature of the support surface of the substrate support assembly to form independently controllable heater zones which are formed to correspond to a desired temperature profile across the upper surface of the semiconductor substrate. The etch rate across the upper surface of the semiconductor substrate during plasma etching depends on a localized temperature thereof wherein the desired temperature profile is determined such that the upper surface of the semiconductor substrate is planarized within a predetermined time. The substrate is plasma etched for the predetermined time thereby planarizing the upper surface of the substrate.
