Patent number: 11987431Abstract: A top-opening substrate carrier comprises a container body, a door member and at least one latching mechanism. The latching mechanism includes a rotary drive member, a first driven cam, a second driven cam, a first connecting rod, a second connecting rod, two longitudinal latching arms and two lateral latching arms. The first driven cam and the second driven cam are disposed at two sides of the rotary drive member. When the rotary drive member is rotated by force, it links and activates the first connecting rod and the second connecting rod to synchronously drive the first driven cam and the second driven cam to rotate, thereby driving the two longitudinal latching arms and the two lateral latching arms to project towards locking holes of the container body and locked, or retract from the locking holes of the container body and unlocked.Type: GrantFiled: March 27, 2023Date of Patent: May 21, 2024Assignee: GUDENG PRECISION INDUSTRIAL CO., LTD.Inventors: Ming-Chien Chiu, Yung-Chin Pan, Cheng-En Chung, Chih-Ming Lin, Po-Ting Lee, Wei-Chien Liu, Tzu-Ning Huang

Patent number: 11916075Abstract: An integrated circuit (IC) structure includes a substrate having several regions, several semiconductor devices formed at the substrate and respectively within the regions, and an ultra-deep (UD) trench isolation structure formed in the substrate. The substrate has a top surface and a bottom surface oppositely, and the UD trench isolation structure formed in the substrate surrounds peripheries of each of the regions for structurally and physically isolating the semiconductor devices within different regions. The UD trench isolation structure penetrates the substrate by extending from the top surface of the substrate to the bottom surface of the substrate.Type: GrantFiled: May 10, 2022Date of Patent: February 27, 2024Assignee: UNITED MICROELECTRONICS CORP.Inventors: Wei-Lun Hsu, Yung-Chien Kung, Ming-Tsung Yeh, Yan-Hsiu Liu, Am-Tay Luy, Yao-Pi Hsu, Ji-Fu Kung

Publication number: 20230386876Abstract: A door locking mechanism and semiconductor container using the same include door panel, cover, and locking module. The door panel has a first stop structure. The cover and the door panel define an accommodating space for receiving the locking module. The locking module includes rotating member, holding member, and elastic member. The elastic member is disposed on the holding member and has a second stop structure near the first stop structure. The elastic member is disposed between the holding and the rotating member. The elastic member is compressed when a force is applied to the holding member, and the second stop structure detaches from a limitation state with the first stop structure for allowing a rotating operation of the rotating member. The elastic member elastically restores when the force is removed, and the second stop structure returns to the limitation state for limiting the rotating operation.Type: ApplicationFiled: April 12, 2023Publication date: November 30, 2023Inventors: MING-CHIEN CHIU, YUNG-CHIN PAN, CHENG-EN CHUNG, CHIH-MING LIN, PO-TING LEE, WEI-CHIEN LIU, TZU-NING HUANG

Publication number: 20220089325Abstract: A modularized large-sized carrier includes at least two body modules, at least one hermetic seal component and a back board. The body modules are connected to each other peripherally and arranged in a depth direction. The hermetic seal component surrounds junctions of the body modules. The back board is disposed behind the last one of the body modules. The modularized large-sized carrier overcomes existing carrier size limitations otherwise caused by injection molding machines and continuously expands in the depth direction to thereby enlarge the airtight storage space of the carrier.Type: ApplicationFiled: July 21, 2021Publication date: March 24, 2022Inventors: MING-CHIEN CHIU, EN-NIEN SHEN, YUNG-CHIN PAN, CHENG-EN CHUNG, PO-TING LEE, WEI-CHIEN LIU, TZU-WEI HUANG

Publication number: 20220093437Abstract: A substrate container with enhanced flow field therein includes a box, at least one offset inflation mechanism and at least one gas diffusion mechanism. The offset inflation mechanism is disposed outside internal receiving space of the box. The offset inflation mechanism has a gaseous chamber extending in the same direction as a bottom panel. The gas diffusion mechanism includes a base, a partition wall and at least one diffusion member. The base masks an outlet of the gaseous chamber to form an auxiliary gaseous chamber. The partition wall extends perpendicularly to the bottom panel to form a vertical first gas channel in communication with the auxiliary gaseous chamber. The diffusion member and the partition wall together define a second gas channel. The partition wall has at least one gap whereby the first gas channel and the second gas channel are in communication with each other.Type: ApplicationFiled: March 10, 2021Publication date: March 24, 2022Inventors: MING-CHIEN CHIU, EN-NIEN SHEN, YUNG-CHIN PAN, CHIH-MING LIN, WEI-CHIEN LIU, CHENG-EN CHUNG, PO-TING LEE, JYUN-YAN JIANG
