  • Patent number: 11401441
    Abstract: Provided are Chemical Mechanical Planarization (CMP) formulations that offer high and tunable Cu removal rates and low copper dishing for the broad or advanced node copper or Through Silica Via (TSV). The CMP compositions provide high selectivity of Cu film vs. other barrier layers, such as Ta, TaN, Ti, and TiN, and dielectric films, such as TEOS, low-k, and ultra low-k films. The CMP polishing formulations comprise solvent, abrasive, at least three chelators selected from the group consisting of amino acids, amino acid derivatives, organic amine, and combinations therefor; wherein at least one chelator is an amino acid or an amino acid derivative. Additionally, organic quaternary ammonium salt, corrosion inhibitor, oxidizer, pH adjustor and biocide are used in the formulations.

  • Publication number: 20220195245
    Abstract: Chemical Mechanical Planarization (CMP) polishing compositions, methods and systems are used to polish low-k or ultra-low-k films with reasonable high removal rates while to polish oxide and nitride films with relative low removal rates. The compositions use 5 abrasive, chemical additives to boost low-k or ultra-low-k film removal rates and suppress oxide and nitride film removal rates for achieving high selectivity, such as low-: TEOS, ultra-low-K: TEOS, and low-k: SiN or ultra-low-k: SiN.

  • Patent number: 11338715
    Abstract: An automotive head restraint apparatus includes a housing having a padded and upholstered exterior, the housing being rotatable about a lateral support tube that supports a lock plate having a lobe extending radially with a detent slot extending therein. A latch finger extends from a pivotable lock lever plate to releasably engage in the detent slot to latch the housing in the deployed position. A pull rod is secured to the lock lever plate, and is connected to a release lever arm at its other end. A shape memory alloy (SMA) wire loop is passed about a drive pulley that is supported by a reciprocally translatable slide. A drive arm extends from the slide to impinge on the release lever and raise the pull rod when the SMA wire loop is energized and contracted, thereby releasing the latch finger to rotate the housing to the retracted position.

  • Publication number: 20220057160
    Abstract: A firearm suppressor is described herein. The firearm suppressor can include a proximal end, a distal end, and a cylindrical body positioned between the proximal end and the distal end. The cylindrical body of the firearm suppressor can include one or more chambers and one or more chamber separators. The distal end can include spiral vanes and exhaust openings that can generate rotational force on the firearm suppressor by redirecting flow of gases exiting the firearm suppressor. The chambers can house a lattice structure in a form of lattice that can split sound waves, pressure waves, and quickly dissipate heat generated within the firearm suppressor.

  • Publication number: 20220042423
    Abstract: A gas turbine engine having a damping system that includes features for optimizing the damping response to vibrational loads on a rotary component for a wide range of operational conditions is provided. In one aspect, the damping system includes a damper control valve. The damper control valve receives working fluid from a working fluid supply and has a valve plunger movable between a first position and a second position. When the valve plunger is in the first position, the damper control valve permits working fluid to flow to a first damper associated with a first bearing coupled with the rotary component and to a second damper associated with a second bearing coupled with the rotary component. When the valve plunger is in the second position, the damper control valve permits working fluid to flow to the first damper but not the second damper.
