Abstract
A bottom loading wafer carrier box provides a cavity which appropriately may have a still and particulate free environment for a wafer carrier handling silicon wafers during their storage,transport, and transfer into and out of processing equipment for the manufacture of semiconductors. The box includes a housing enclosing the cavity with an open bottom suitable for receiving the wafer carrier into the cavity. A releaseable door is provided for sealing the open bottom from the ambient environment about the housing of the box. A cam bar is slideably connected to the outside of the housing and operably connected to a moveable slider extending within the cavity. The slider has a carrier catch adapted for retaining the wafer carrier within the cavity and a cushion to retain the wafers within the carrier and to reduce the effects of shock upon the wafers. A grippable handle suitably extends from the cam bar so that the handle is operably connected to the slider to manually actuate engagement of the catch with the carrier and the cushion with the wafers.
