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.

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.

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.

Abstract: A lift pin includes a lift pin body arranged along a lift pin axis having a contact pad, a stem segment, a neck segment, and a span feature. The contact pad is defined at a first end of the lift pin body, the stem segment extends from the contact pad, and the neck segment extends from the stem segment. The span feature is defined at a second end of the lift pin body, is connected to the contact pad by the neck segment and the stem segment, and has a minor and major widths. The minor width is equivalent to a neck diameter defined by the neck segment, the major with is greater than the minor width, and the major width is greater than a stem diameter defined by the stem segment. Lift pin arrangements, semiconductor processing systems, and methods of making semiconductor processing systems are also described.

Abstract: A reflector includes a reflector body having a slotted surface, a planar surface, and an ellipsoidal surface. The planar surface is opposite the slotted surface and is separated from the slotted surface by a thickness of the reflector body. The ellipsoidal surface is offset from the planar surface, is opposite the slotted surface and separated from the slotted surface by the thickness of the reflector body and spans the slotted surface of the reflector body. The ellipsoidal surface defines an elliptical profile that is orthogonal relative to the planar surface to concentrate heat flux at a distal focus of the elliptical profile using electromagnetic radiation reflected by the ellipsoidal surface of the reflector body. Semiconductor processing systems and material layer deposition methods are also described.
