  • Publication number: 20240088071
    Abstract: Methods for reducing resistivity of metal gapfill include depositing a conformal layer in an opening of a feature and on a field of a substrate with a first thickness of the conformal layer of approximately 10 microns or less, depositing a non-conformal metal layer directly on the conformal layer at a bottom of the opening and directly on the field using an anisotropic deposition process. A second thickness of the non-conformal metal layer on the field and on the bottom of the feature is approximately 30 microns or greater. And depositing a metal gapfill material in the opening of the feature and on the field where the metal gapfill material completely fills the opening without any voids.

  • Patent number: 8714515
    Abstract: A hydraulic actuating device for a sliding stem control valve assembly is mounted between a control valve and an actuator housing. The hydraulic actuating device is connected to one of a control valve stem, an actuator stem, and a stem connector and the hydraulic actuating device moves either the control valve stem, the actuator stem, or the stem connector in response to varying hydraulic pressure within the hydraulic actuating device. The hydraulic actuating device may be used to override an actuator of the sliding stem valve during emergency operations, or to provide a backup actuator in the case of a primary actuator malfunction.
