  • Publication number: 20240112930
    Abstract: A chamber arrangement includes a chamber body, a substrate support, and a laser source. The substrate support is arranged within the chamber body and supported for rotation about a rotation axis relative to the chamber body. The laser source is arranged outside of the chamber body and optically coupled to the substrate support along a lasing axis. The lasing axis intersects the substrate support at a location radially outward from an outer periphery of a substrate seated on the substrate support. A semiconductor processing system and a material layer deposition method are also described.

  • Publication number: 20240071804
    Abstract: Methods, systems, and assemblies suitable for gas-phase processes are disclosed. An exemplary assembly includes a susceptor ring and at least one injector tube. The injector tube can be disposed within the susceptor ring to provide a gas to a peripheral region of a substrate. Methods, systems, and assemblies can be used to obtain desired (e.g. composition and/or thickness) profiles of material on a substrate surface.

  • Publication number: 20240071805
    Abstract: Methods, systems, and assemblies suitable for gas-phase processes are disclosed. An exemplary assembly includes a susceptor ring and at least one injector tube. The injector tube can be disposed within the susceptor ring to provide a gas to a lower chamber area of a reactor. Methods, systems, and assemblies can be used to obtain desired etching and purging of the lower chamber area.

  • Publication number: 20230307255
    Abstract: A semiconductor processing system includes a chamber arrangement, an exhaust arrangement connected to the chamber arrangement, an accretion sensor supported within the exhaust arrangement, and a processor. The processor is disposed in communication with the accretion sensor and is responsive to instructions recorded on a non-transitory machine-readable medium to receive an accretion signal from the accretion sensor, the accretion signal indicative of an accretion amount disposed within the exhaust arrangement, receive a predetermined accretion amount value, and compare the accretion amount to the predetermined accretion amount value. The instructions further cause the processor to execute an accretion countermeasure when the received accretion amount is greater than the predetermined accretion amount value. Methods of controlling accretion within exhaust arrangements for semiconductor processing systems and foreline assemblies for semiconductor processing systems are also described.

  • Publication number: 20220301905
    Abstract: A method of operating a reactor system to provide multi-zone substrate temperature control. The method includes, with a first pyrometer, sensing a temperature of a first zone of a substrate supported in the reactor system, and, with a second pyrometer, sensing a temperature of a second zone of the substrate. The method further includes, with a controller, comparing the temperatures of the first and second zones to setpoint temperatures for the first and second zones and, in response, generating control signals to control heating of the substrate. The method also includes controlling, based on the control signals, operations of a heater assembly operating to heat the substrate.

  • Publication number: 20220189804
    Abstract: A fixture includes a frame, a leveling plate, a bracket, and a laser profiler. The frame is arranged for fixation above a reaction chamber arranged to deposit a film onto a substrate. The leveling plate is supported on the frame. The bracket is supported on the leveling plate. The laser profiler is suspended from the bracket, overlays the reaction chamber, and has a field of view that extends through the leveling plate and the frame to determine position of a target within the reaction chamber. Semiconductor processing systems and methods of determining position of targets within reaction chambers in semiconductor processing systems are also described.

  • Publication number: 20220181193
    Abstract: A substrate support and lift assembly configured to support and lift a substrate from a susceptor is disclosed. The substrate support and lift assembly can include a susceptor support and a lift pin. The susceptor support can be configured to support the susceptor thereon. The susceptor support includes a plurality of support arms each extending radially from a central portion of the susceptor support to a terminus. Each of the plurality of support arms includes an aperture extending therethrough. The lift pin can be configured to fit through the aperture of a corresponding support arm to lift a substrate on the susceptor.

  • Publication number: 20200131634
    Abstract: A coating and a method to form the coating is proposed for a semiconductor film pre-clean and etch apparatus. The coating may be employed in environments where it is difficult to use a traditional coating or coating method. The coatings provide advantages including: an ability to effectively deliver hydrogen radicals and fluorine radicals to a wafer surface in one apparatus or individually in two apparatuses; a coverage of high aspect ratio features on critical components; an operability in high temperatures exceeding 150° C.; and a protection of a part with high aspect ratio features underneath the coating, thereby preventing metal and particles on a processed wafer.
