Publication number: 20210358787Abstract: The invention discloses a reticle pod having a lid and multiple pin assemblies. The pin assembly includes a movable member movable relatively to a ceiling of the lid and an elastic member configured to arrange the movable member in between the elastic member and the ceiling of the lid. In the case where the reticle pod is provided without receiving a reticle, the ceiling of the reticle pod determines the movable member stays at a first level. In the case where the reticle pod is provided with a reticle, the elastic member collaborates with the movable member such that the movable member holds the reticle at a second level that is higher than the first level.Type: ApplicationFiled: January 12, 2021Publication date: November 18, 2021Inventors: Ming-Chien CHIU, Chia-Ho Chuang, Hsing-Min Wen, Yi-Hsuan Lee, Hsin-Min Hsueh

Patent number: 11175579Abstract: A reticle pod includes a body, cover, sliding-rail member, sliding-fastening member and shut-corresponding element. The sliding-rail member has a dent portion and a slot portion and defines a locked direction. The dent portion extends from the slot portion in the locked direction. The sliding-fastening member is slidably disposed at the sliding-rail member. The sliding-fastening member has a fastening portion and resilient arms. The resilient arms are inserted into a slot of the slot portion. The fastening portion has a fastening groove corresponding in height to the slot portion. An oblique-guide surface is disposed above the fastening groove. When the cover switches from an open state to a closed state, the shut-corresponding element pushes the sliding-fastening member across the oblique-guide surface and thus compresses the sliding-fastening member, allowing the shut-corresponding element to enter the fastening groove.Type: GrantFiled: May 18, 2020Date of Patent: November 16, 2021Assignee: GUDENG PRECISION INDUSTRIAL CO., LTD.Inventors: Chia-Ho Chuang, Hsin-Min Hsueh, Yu-Chen Chu, Ming-Chien Chiu

Publication number: 20200335371Abstract: A reticle pod with a spoiler structure includes a body and a cover. A reticle allocation area is centrally disposed at the body. The cover covers the body. A peripheral area of the cover and a peripheral area of the body are fitted together by a protruding portion and a dented portion. The dented portion and the protruding portion jointly form a spoiler structure surrounding the reticle allocation area. The spoiler structure includes a spoiler passage between the dented portion and the protruding portion. The body has at least one retreated sidewall corresponding in position to the spoiler passage to form a particle-collecting space. Particles carried by external air current which enters the spoiler passage end up in the particle-collecting space and thus are denied entry into the reticle allocation area.Type: ApplicationFiled: September 6, 2019Publication date: October 22, 2020Inventors: CHIA-HO CHUANG, HSIN-MIN HSUEH, SHU-HUNG LIN, MING-CHIEN CHIU
