Patents by Inventor Christopher William Burkhart

Christopher William Burkhart has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11282737
    Abstract: A substrate processing tool includes a plurality of process modules configured to process a semiconductor substrate. Each of the plurality of process modules is arranged at a different location within the substrate processing tool. A vacuum transfer module (VTM) includes a robot and is configured to move between a plurality of different positions corresponding to the different locations within the substrate processing tool to allow the robot to access respective ones of the plurality of process modules.
    Type: Grant
    Filed: February 15, 2019
    Date of Patent: March 22, 2022
    Assignee: Lam Research Corporation

  • Patent number: 10794519
    Abstract: Methods and apparatuses for additively manufactured tubular passages, additively manufactured manifolds, and additively manufactured heaters are provided.
    Type: Grant

  • Patent number: 10483142
    Abstract: A system for mounting vacuum robot arms in horizontally elongate vacuum transfer modules is provided. The system provides mechanical isolation to the vacuum robot arm against deflections in the housing of the vacuum transfer module due to depressurization of the interior of the vacuum transfer module while the exterior of the vacuum transfer module is subjected to atmospheric pressure. Such systems may prevent undesirable, larger displacements of the end effector of such vacuum robot arms due to the deflection.

  • Patent number: 9879795
    Abstract: A manifold constructed by additive manufacturing for use in semiconductor processing tools is provided. The manifold may include a mixing chamber and portions of a plurality of flow paths with each flow path including a first fluid flow component interface, a second fluid flow component interface, a first tubular passage fluidically connecting the first mixing chamber with a first fluid flow component interface outlet of that flow path, and a second tubular passage fluidically connecting a first fluid flow component interface inlet of that flow path with a second fluid flow component interface outlet of that flow path. Each fluid flow component interface is configured to interface with a corresponding fluid flow component such that the corresponding fluid flow component, when installed, is able to interact with fluid flow between the fluid flow component interface inlet and the fluid flow component interface outlet.
