  • Patent number: 11511219
    Abstract: Filter cartridges and manifold blocks for filter manifold systems are described. The filter cartridges include flanges surrounding openings at first and second ends of the filter cartridge, with face seals in the flanges. Manifold blocks include end blocks, at least one of which is movable so that the distance between the end blocks can be changed. When a filter cartridge is installed into the manifold by engagement of the flanges with slots in the manifold end blocks, a fluid pathway is formed through a first manifold end block, into the filter cartridge, through the filter cartridge, out of the filter cartridge and into a second manifold end block. The fluid pathway is sealed by the face seals where the flow is from a manifold end block into or out of the filter cartridge.

  • Patent number: 11476158
    Abstract: A process for forming cobalt on a substrate, comprising: volatilizing a cobalt precursor of the disclosure, to form, a precursor vapor: and contacting the precursor vapor with the substrate under vapor deposition conditions effective for depositing cobalt on the substrate from the precursor vapor, wherein the vapor deposition conditions include temperature not exceeding 200° C., wherein: the substrate includes copper surface and dielectric material, e.g., ultra-low dielectric material. Such cobalt deposition process can be used to manufacture product articles in which the deposited cobalt forms a capping layer, encapsulating layer, electrode, diffusion layer, or seed for electroplating of metal thereon, e.g., a semiconductor device, flat-panel, display, or solar panel. A cleaning composition containing base and oxidizing agent components may be employed to clean the copper prior to deposition of cobalt thereon, to achieve substantially reduced defects in the deposited cobalt.

  • Patent number: 11466038
    Abstract: Provided is a plasma enhanced atomic layer deposition (PEALD) process for depositing etch-resistant SiOCN films. These films provide improved growth rate, improved step coverage and excellent etch resistance to wet etchants and post-deposition plasma treatments containing O2 and NH3 co-reactants. This PEALD process relies on one or more precursors reacting in tandem with the plasma exposure to deposit the etch-resistant thin-films of SiOCN. The films display excellent resistance to wet etching with dilute aqueous HF solutions, both after deposition and after post-deposition plasma treatment(s). Accordingly, these films are expected to display excellent stability towards post-deposition fabrication steps utilized during device manufacturing and build.
