Publication number: 20230307275Abstract: A purge port assembly for a wafer container includes a purge module configured to allow inlet flow of purge gas and a transition portion disposed over an intermediate outlet of the purge module. The transition portion includes a receiver configured to receive the purge gas discharged from the purge module, an outlet connector configured to attach with a diffuser, and an intermediate conduit. The intermediate conduit connects the receiver to the outlet connector and extends from the receiver at an acute angle relative to an axis of the inlet opening of the receiver. The intermediate conduit has a length that spaces apart the outlet connector from the receiver. A wafer container includes a shell and a purge port assembly. The shell includes an interior space. The purge port assembly extends through an opening in the shell into the interior space.Type: ApplicationFiled: March 23, 2023Publication date: September 28, 2023Inventors: Matthew A.

Publication number: 20230131451Abstract: Substrate containers include purge flow distribution systems. The purge flow distribution systems can divide one or more input flows of purge gas to a plurality of gas distribution surfaces of a network of gas distribution devices. Methods of controlling purge can include configuring the substrate containers to provide determined purge gas flow rates at each of the gas distribution surfaces. The configuration can be performed using flow controls of the purge flow distribution systems. The purge gas flow rates can be determined based on purge performance parameters. A controller can direct the operation of the purge flow distribution systems. The controller and the substrate container can be combined in a substrate container purging system.Type: ApplicationFiled: October 24, 2022Publication date: April 27, 2023Inventors: Matthew A.

Patent number: 11587810Abstract: Wafer cushions for use in wafer carriers include spring beams that include a first arm extending from the frame of the wafer cushion in a first direction and a second arm extending from the first arm in a second direction, and a wafer contact at the end of the second arm opposite where the second arm is joined to the first arm. The wafer cushion may contact a substrate within the wafer carrier only at the wafer contacts during normal conditions. The substrate may also contact secondary contact points on the second arm when a shock event occurs. The wafer contact can be v-groove style wafer contact. The wafer contact may include a contact surface having a convex surface where it is configured to contact the wafer.Type: GrantFiled: July 15, 2020Date of Patent: February 21, 2023Assignee: ENTEGRIS, INC.Inventors: Colton J. Harr, Matthew A. Fuller

Publication number: 20220388751Abstract: In a wafer container, diffusers are positioned such that they are closer to a center line of the wafer container. This improves the distribution of purge gas within the wafer container. The diffusers can be positioned such that their position corresponds to a recessed central panel of the back wall. The diffusers can be positioned such that an angle between the diffusers relative to a center of a wafer contained within the wafer container is 60 degrees or less. The diffusers can be joined to purge ports by offset connectors oriented such that the diffusers are closer to the center line of the wafer container than the purge ports. The distance from each of the diffusers to the center line of the wafer container can be less than one fourth of a diameter of the wafer that the wafer container is configured to accommodate.Type: ApplicationFiled: June 8, 2022Publication date: December 8, 2022Inventors: Matthew A.

Publication number: 20220208582Abstract: Optimizing purge flow parameters in a substrate container, includes streaming a purge working fluid into an interior of the substrate container, discharging the purge working fluid from the interior of the substrate container, and varying purge flow parameters of the purge working fluid for a predetermined period of time, detecting at least one environmental condition in the interior of the substrate container during the predetermined period of time, determining optimized purge flow parameters based on the varied purge flow parameters and the at least one detected environmental condition during the predetermined period of time, and adjusting the streaming and the discharging in accordance with the optimized purge flow parameters. The substrate container may include, for example, a front opening unified pod or a reticle pod.Type: ApplicationFiled: December 29, 2021Publication date: June 30, 2022Inventors: Matthew A.

Patent number: 10872795Abstract: A substrate retainer (110) is provided which presents a substantially uniform contact face (128) that can accommodate a large variation in the location of substrate registration thereon. The uniform contact face (128) is allowed to deflect and compress in order to eliminates the prospect of substrates (114) being damaged by or becoming inadvertently pinched within the substrate retainer (110) or from being pressed too hard by the uniform contact face (128). With this arrangement, no adhesives or tapes are utilized, so there is no attendant out gassing of volatile organic compounds to contaminate the microenvironment, or complications due to incompatibility of such adhesives and tapes with washing processes.Type: GrantFiled: February 3, 2017Date of Patent: December 22, 2020Assignee: ENTEGRIS, INC.Inventors: Matthew A.
