  • Publication number: 20230069317
    Abstract: Exemplary substrate processing systems may include a chamber body defining a transfer region. The systems may include a lid plate seated on the chamber body. The lid plate may define a first plurality of apertures and a second plurality of apertures. The systems may include a plurality of lid stacks equal to a number of the first plurality of apertures. Each lid stack may include a choke plate seated on the lid plate along a first surface of the choke plate. The choke plate may define a first aperture axially aligned with an associated aperture of the first plurality of apertures. The choke plate may define a second aperture axially aligned with an associated aperture of the second plurality of apertures. The choke plate may define protrusions extending from each of a top and bottom surface of the choke plate that are arranged substantially symmetrically about the first aperture.

  • Patent number: 11515176
    Abstract: Exemplary substrate processing systems may include chamber body defining a transfer region. The systems may include a lid plate seated on the chamber body. The lid plate may define a first plurality of apertures through the lid plate and a second plurality of apertures through the lid plate. The systems may include a plurality of lid stacks equal to a number of apertures of the first plurality of apertures defined through the lid plate. Each lid stack of the plurality of lid stacks may include a choke plate seated on the lid plate along a first surface of the choke plate. The choke plate may define a first aperture axially aligned with an associated aperture of the first plurality of apertures. The choke plate may define a second aperture axially aligned with an associated aperture of the second plurality of apertures.

  • Patent number: 11371148
    Abstract: A method includes receiving one or more parameters associated with a plurality of metal plates. The method further includes determining, based on the one or more parameters, a plurality of predicted deformation values associated with the plurality of metal plates. Each of the plurality of predicted deformation values correspond to a corresponding metal plate of the plurality of metal plates. The method further includes causing, based on the plurality of predicted deformation values, the plurality of metal plates to be diffusion bonded to produce a bonded metal plate structure.

  • Publication number: 20190311886
    Abstract: Plasma source assemblies, gas distribution assemblies including the plasma source assembly and methods of generating plasma are described. The plasma source assemblies include a powered electrode with a ground electrode adjacent a first side, a first dielectric adjacent a second side of the powered electrode and at least one second dielectric adjacent the first dielectric on a side opposite the first dielectric. The sum of the thicknesses of the first dielectric and each of the second dielectrics is in the range of about 10 mm to about 17 mm.
