Abstract:
1. A containment device for retaining semiconductor wafers, comprising: a base including at least one cylindrical wall extending therefrom, said at least one cylindrical wall forming a wafer containment area therewithin, at least a portion of said at least one cylindrical wall being segmented thereby forming slots within said at least one cylindrical wall, said slots receiving spacer elements which extend into said wafer containment area thereby positioning a plurality of semiconductor wafers away from said at least one cylindrical wall; said spacer elements comprising a flexible material, whereby said spacer elements can be installed after a plurality of semiconductor wafers have been placed in said wafer containment area and further whereby said spacer elements can be removed prior to removal of the plurality of semiconductor wafers; and a lid which includes means for engaging said base, said lid forming a top of the containment device when said base and said lid are attached together.
