    Abstract: A method of forming a tungsten-containing layer over a substrate includes a) positioning a substrate on a substrate support in a process volume of a process chamber; b) providing a precursor gas to the process volume of the process chamber for a first duration; and c) providing a tungsten-containing gas to the process volume of the process chamber by opening a pulsing valve on a tungsten-containing gas delivery line for a second duration occurring after the first duration to form a tungsten-containing layer on the substrate. The tungsten-containing gas delivery line includes a first section connected to an inlet of the pulsing valve and a second section connected to an outlet of the pulsing valve, the first section connects the inlet of the pulsing valve to a reservoir of tungsten-containing gas, the second section connects the outlet of the pulsing valve to an inlet of the process chamber.

    Abstract: Methods and systems for controlling concentration profiles of deposited films using machine learning are provided. Data associated with a target concentration profile for a film to be deposited on a surface of a substrate during a deposition process for the substrate is provided as input to a trained machine learning model. One or more outputs of the trained machine learning model are obtained. Process recipe data identifying one or more sets of deposition process settings is determined from the one or more outputs. For each set of deposition process setting, an indication of a level of confidence that a respective set of deposition process settings corresponds to the target concentration profile for the film to be deposited on the substrate is also determined. In response to an identification of the respective set of deposition process settings with a level of confidence that satisfies a level of confidence criterion, one or more operations of the deposition process are performed in accordance with the respective set of deposition process settings.

    Abstract: A system may include a main line for delivering a first gas, and a sensor for measuring a concentration of a precursor in the first gas delivered through the main line. The system may further include first and second sublines for providing fluid access to first and second processing chambers, respectively. The first subline may include a first flow controller for controlling the first gas flowed through the first subline. The second subline may include a second flow controller for controlling the first gas flowed through the second subline. A delivery controller may be configured to control the first and second flow controllers based on the measured concentration of the precursor to deliver a first mixture of the first gas and a second gas and a second mixture of the first and second gases into the first and second semiconductor processing chambers, respectively.

    Abstract: Embodiments of the present disclosure generally relate to chemical mechanical polishing (CMP) of substrates. In one embodiment, a carrier head for a CMP apparatus is disclosed herein. The carrier head includes a body, a retaining ring, and a sensor assembly. The retaining ring is coupled to the body. The sensor assembly is positioned at least partially in the body. The sensor assembly includes a transmitter, an antenna, and a vibrational sensor. The transmitter has a first end and a second end. The antenna is coupled to the first end of the transmitter. The vibrational sensor is coupled to the second end. The vibrational sensor is configured to detect vibration during chemical mechanical processes with respect to radial, azimuthal, and angular axes of the carrier head.

    Abstract: Exemplary semiconductor processing systems may include a chamber body comprising sidewalls and a base. The systems may include a substrate support extending through the base of the chamber body. The substrate support may include a support plate defining a plurality of channels through an interior of the support plate. Each channel of the plurality of channels may include a radial portion extending outward from a central channel through the support plate. Each channel may also include a vertical portion formed at an exterior region of the support plate fluidly coupling the radial portion with a support surface of the support plate. The substrate support may include a shaft coupled with the support plate. The central channel may extend through the shaft. The systems may include a fluid source coupled with the central channel of the substrate support.
