Definitions

  • the present disclosure relates generally to containers for storing, transporting, shipping and/or processing fragile devices such as photomasks, reticles and wafers, and more particularly to a dual containment reticle pod having an inner pod incorporating a reticle retainer that limits or restricts movement in the X and Y directions in an effort to minimize particle generation within the pod.
