Abstract:
1. A container for semiconductor wafers, comprising: a base; an upwardly open hollow cylindrical structure supported on the base and defining a cavity with a generally planar bottom for receiving a given maximum number of stacked wafers circumferentially restrained therein; a top cover removably attached to the base and over the cylindrical structure, the cover providing a generally planar top for the cavity; a plurality of disk shaped objects having an outer diameter, wherein the outer diameter of the disk shaped objects is equal to or less than the inner diameter of the cavity; and a single vertically deformable packing insert including: the circular portion and the cantilever portions being dimensioned and configured so that the vertically deformable packing insert will elastically compress or expand in a vertical direction to at least vertically restrain the stacked wafers within the cavity, contacting only a top disk shaped object of the plurality of disk shaped objects, wherein the top disk shaped object is itself in contact with topmost wafer of the stacked wafers therein, and a bottom disk shaped object in contact with a bottom wafer, the bottom disk shaped object also in contact with the base.
