  • Publication number: 20250208526
    Abstract: A photolithography substrate container includes an inlet configured to receive purge gas, baffles, a photolithography substrate accommodation space, and an outlet for the purge gas. The baffles can affect the flow of purge gas received at the inlet to control flow rates, pressure differentials, and the like for the flow of purge gas through the photolithography substrate accommodation space. The baffles can be provided between the inlet and the photolithography substrate accommodation space. The baffles can be included on one or more parts of the photolithography substrate container or on an insert configured to be attached thereto.

  • Patent number: 12326659
    Abstract: Reticle containers include a magnetic latch to close the container and clamp the reticle contained within. The magnetic latch includes at least one magnet and another ferromagnetic material, which can be either another magnet or a magnetically attractable material. At least one of the magnets and the other ferromagnetic material can be manipulated to secure or open the container. The manipulation can include at least one of sliding of a housing, rotation of a magnet, or application of an external magnetic field to change the attraction of the magnet and the other ferromagnetic material.

  • Patent number: 12271110
    Abstract: Reticle pods include interfacing surfaces to secure segments of the reticle pod to one another. At least one of the interfacing surfaces is a ramped surface, such that when the reticle pods are secured to one another, the reticle is clamped between reticle contacts provided on the segments of the reticle pod. When the reticle pod is assembled and contains a reticle, a purge gas flow passage can be formed in the reticle pod. The height of the reticle contacts and the thickness of the reticle can be such that the reticle pod segments are spaced apart from one another by a gap, with the gap providing the purge gas flow passage. The reticle pod can be a stocker pod for the transportation and storage of reticles.

  • Publication number: 20240061326
    Abstract: Reticle containers include a cover and a baseplate having contact surfaces configured to contact one another when the reticle container is assembled. Relief areas are provided adjacent to at least one of the contact surfaces. The relief areas are such that plating provided on in those relief areas do not contact the other of the cover or the baseplate when the reticle container is assembled. The relief areas can include structures such as beveled regions, depressions, and radiused regions. The relief areas can optionally further serve as a robber during an electroplating process.
