Patent number: 11166441Abstract: A chemical precursor container is disclosed. The container includes a vessel and a lid that define an interior volume, an inlet conduit, an outlet conduit, and a flow distributor positioned inside the vessel and in fluid flow communication with the inlet conduit. The flow distributor has an annular shape and includes a distributor floor having a plurality of apertures formed therein for expelling carrier gas therethrough. The flow distributor includes an inner annular wall that defines a porthole in the flow distributor that allows fluid to pass through the flow distributor from the interior volume of the vessel to the outlet conduit.Type: GrantFiled: June 28, 2019Date of Patent: November 9, 2021Assignee: Versum Materials US, LLCInventors: Charles Michael Birtcher, Robert Eschbach, William Jon Sheehy, James Patrick Nehlsen

Patent number: 10563305Abstract: Described herein are systems and methods using same for the storage and delivery of chemical precursors that are used in the manufacture of a semiconductor device. In one aspect, the storage system comprises the chemical precursors and a container and the systems have an inlet jet design. The chemical precursor has a low vapor pressure less than about 50 Torr-absolute at container temperature set for delivery. The delivery system further contains a carrier gas. The inlet jet design can deliver the carrier gas at a certain pressure and a certain low rate to impinge upon the surface of the chemical precursors to produce a vapor or droplets of the chemical precursor. The vapor or droplets of the chemical precursor then combine with the carrier gas to provide a precursor-laden fluid stream which will be passed to and used in the processing tool.Type: GrantFiled: April 29, 2016Date of Patent: February 18, 2020Assignee: VERSUM MATERIALS US, LLCInventors: James Patrick Nehlsen, Charles Michael Birtcher

Patent number: 10480070Abstract: Described herein are delivery containers, systems and methods using same for providing improvements to precursor utilization in the containers for deposition process, as well as the cleaning and refilling of the containers. The containers are designed with structures which allow a carrier gas to be delivered from a flow distributor. The flow distributor comprises a plurality of small openings (jets) through which the carrier gas enters the precursor chamber and impinges upon the surface of the chemical precursors to produce a vapor.Type: GrantFiled: May 4, 2017Date of Patent: November 19, 2019Assignee: VERSUM MATERIALS US, LLCInventors: Charles Michael Birtcher, James Patrick Nehlsen, Sergei Vladimirovich Ivanov, Thomas Andrew Steidl, Kai Kang, Wade Hampton Bailey, III

Publication number: 20140110269Abstract: A process and an anode for the production of nitrogen trifluoride or fluorine where the anode in the electrolytic cell is made primarily from parallel ordered anisotropic carbon, including needle coke and/or mesocarbon microbeads. The parallel ordered anisotropic carbon anodes minimize the production of CF4 and improve the purity of the nitrogen trifluoride or fluorine gas produced. Additionally, the anodes may be molded, instead of extruded or machined, providing for improved dimensional and mechanical integrity of the anode.Type: ApplicationFiled: October 4, 2013Publication date: April 24, 2014Applicant: Air Products and Chemicals, Inc.Inventors: James Patrick Nehlsen, Kerry Renard Berger, Reinaldo Mario Machado, Kyoung-Ho Choi
