  • Patent number: 12272595
    Abstract: A method includes depositing a mask layer over a dielectric layer, patterning the mask layer to form a trench, applying a patterned photo resist having a portion over the mask layer, and etching the dielectric layer using the patterned photo resist as an etching mask to form a via opening, which is in a top portion of the dielectric layer. The method further includes removing the patterned photo resist, and etching the dielectric layer to form a trench and a via opening underlying and connected to the trench. The dielectric layer is etched using the mask layer as an additional etching mask. A polymer formed in at least one of the trench and the via opening is removed using nitrogen and argon as a process gas. The trench and the via opening are filled to form a metal line and a via, respectively.

  • Patent number: 11736510
    Abstract: A domain security assurance system includes a computing platform having processing hardware and a memory storing software code. The processing hardware is configured to execute the software code to obtain domain inventory data identifying multiple domains, to predict, using the domain inventory data, which of the domains are owned by the same entity to identify commonly owned domains, and to determine, using the domain inventory data and the commonly owned domains, which of the commonly owned domains are controlled by the same administrator to identify one or more group(s) of commonly administered domains. When executed, the software code also removes, using the domain inventory data, duplicate domains included in the group(s) to identify non-duplicate domains, evaluates a susceptibility of each of the non-duplicate domains to a cyber-attack to identify one or more target domain(s) vulnerable to the cyber-attack, and identifies the target domain(s) for a security assessment.
