  • Publication number: 20210118668
    Abstract: The present disclosure pertains to embodiments of a semiconductor deposition reactor manifold and methods of using the semiconductor deposition reactor manifold which can be used to deposit semiconductor layers using processes such as atomic layer deposition (ALD). The semiconductor deposition reactor manifold has a bore, a first supply channel, and a second supply channel. Advantageously, the first supply channel and the second supply channel merge with the bore in an offset fashion which leads to reduced cross-contamination within the supply channels.

  • Publication number: 20200373187
    Abstract: A workpiece susceptor body can include a front face configured to support a workpiece, a back face opposite the front face, a workpiece contact zone at least partially forming a support boundary on an inner portion of the front face, and a plurality of axial channels disposed within the susceptor body. The workpiece contact zone can be disposed radially inward of an outer edge of a workpiece positioned on the front face in a processing configuration. Each of the plurality of axial channels may connect to corresponding openings extending into an outer portion of the front face. Each of the openings may be disposed radially outward of the workpiece contact zone of the susceptor body.

  • Publication number: 20200354836
    Abstract: A chemical vessel is disclosed comprising a dip tube and a level sensor tube arranged in an elongated counterbore incorporated into a housing of the chemical vessel. The chemical vessel may be configured to allow a pushback routine to take place, whereby a level of liquid in the chemical vessel is reduced to a point that the dip tube is free from liquid inside the dip tube or at the bottom of the dip tube. Once the dip tube is free of the liquid, then a vacuum source may be used to purge vapor within the chemical vessel without the risk of damage to the vacuum source.

  • Publication number: 20200299836
    Abstract: Herein disclosed are systems and methods related to semiconductor processing device including a manifold including a bore configured to deliver a gas to a reaction chamber, the manifold including a first block mounted to a second block, the first and second mounted blocks cooperating to at least partially define the bore. A supply channel provides fluid communication between a gas source and the bore, and the supply channel is disposed at least partially in the second block. A metallic seal is disposed about the bore at an interface between the first and second block. Advantageously, the metallic seal improves sealing between the interface between the first block and the second block.

  • Patent number: 10683571
    Abstract: A gas inlet system for a wafer processing reactor includes a tubular gas manifold conduit adapted to be connected to a gas inlet port of the wafer processing reactor; and gas feeds including a first feed for feeding a first gas into the tubular gas manifold conduit and a second feed for feeding a second gas into the tubular gas manifold conduit. Each feed has two or more injection ports connected to the tubular gas manifold conduit at a first axial position of the tubular gas manifold conduit, and the injection ports of each of the gas feeds are evenly distributed along a circumference of the tubular gas manifold conduit at the first axial position.

  • Publication number: 20190157054
    Abstract: Multi-zone reactors, systems including a multi-zone reactor, and methods of using the systems and reactors are disclosed. Exemplary multi-zone reactors include a movable susceptor assembly and a moveable plate. The movable susceptor assembly and movable plate can move vertically between reaction zones of a reactor to expose a substrate to multiple processes or reactants.
