  • Patent number: 11442370
    Abstract: A reticle retaining system including an inner pod and an outer pod is described. The inner pod includes an inner base configured to receive a workpiece; an inner cover configured to couple to the inner base, thereby forming an interior for housing the workpiece; and a hold down pin movably arranged through the inner cover and configured to press the workpiece. The outer pod includes an outer base configured to receive the inner base, an outer cover configured to couple to the outer base, and a pushing element arranged on the outer cover. The hold down pin, the outer cover and the pushing element have a charge dissipation property. When the pushing element pushes the hold down pin to press the workpiece, a charge dissipation path is established from the received workpiece, through the hold down pin and the pushing element, to the outer cover.

  • Publication number: 20220102177
    Abstract: A reticle pod with antistatic capability includes a base and plural of support members. The base has a carrying surface having a recess formed thereon and defined by a bottom surface. The support members encircle the carrying surface of the base and are adapted to support a reticle. The recess is defined by a depth extending between the carrying surface and the bottom surface. The depth ranges from 300 ?m to 3400 ?m to thereby weaken the electrostatic force exerted upon particles on the carrying surface.
