Abstract:
A reticle pressing unit and an EUV reticle pod using the same are provided. An inner assembly includes an upper cover and a lower cover. The lower cover includes a supporting element for supporting the reticle. A pressing unit for pressing the reticle is disposed on the upper cover and includes a pressing element and a limiting cap. The pressing element has oppositely arranged pressing part and pressure receiving part. The pressing part extends through the upper cover to press against the reticle. The pressing element is covered by the limiting cap and is protruded outwardly from a top surface of the limiting cap. An outer cover has a pushing surface for forming a surface-to-surface contact with the pressure receiving part and for simultaneously pressing against the pressure receiving part and the top surface to solve the problems relating to the reticle which is applied with uneven forces.
