Packaging epitaxially coated semiconductor disks

Abstract

Abstract A package for storing and shipping epitaxially coated semiconductor disks comprising a plurality of similar trays which are adapted to be nested one on top of the other. An upstanding vertical rim extends about the upper face of each of the trays and a narrow horizontal ledge extends about each of said trays beneath said rim. A second rim projects vertically downward from the outer edge of the horizontal ledge of each tray, and this rim fits snugly over and frictionally engages the upstanding rim of the tray which is stacked therebeneath. The upper face of each tray contains upstanding partitions which form a plurality of similar storage compartments in the tray. Each of said compartments has a flat horizontal floor and a circular dished portion for storing a semiconductor disk within such compartment. The said dished portion, which constitutes most of the floor of each compartment, has an outer rim sunk slightly below the outer flat part of the floor to restrain the semiconductor disk from being dislodged when said tray is placed on an incline. A cover is provided for the topmost tray, and a plurality of downwardly curved resilient petals are provided on the bottom of each tray for resiliently holding each semiconductor disk in its assigned storage compartment. Means are also provided to facilitate the insertion of forceps or tongs into the various compartments, when the nested trays are unstacked, to permit the semiconductor disks to be readily removed.
