  • Patent number: 11037825
    Abstract: Apparatuses and methods to provide a fully self-aligned via are described. Some embodiments of the disclosure utilize a cap layer to protect an insulating layer in order to minimize bowing of the side walls during metal recess in a fully self-aligned via. The cap layer can be selectively removed, thus increasing the aspect ratio, by exposing the substrate to a hot phosphoric acid solution.

  • Publication number: 20180221949
    Abstract: An additive manufacturing system includes a platen, a dispenser configured to deliver a powder in a linear region that extends across less than all of a width of the platen, a drive system configured to move the dispenser along the first axis and a perpendicular second axis, a controller, and an energy source configured to selectively fuse a layer of powder. The controller is configured to cause the drive system to move the dispenser along the second axis a first time such that the linear region makes a first sweep along the second axis to deposit the powder in a first swath over the platen, thereafter along the first axis, and thereafter along the second axis a second time such that the first linear region makes a second sweep along the second axis to deposit the powder in a parallel second swath over the platen.
