ABSTRACT:
A semiconductor wafer container comprises two identical parts, one forming the bottom and the other forming the lid. Each part has the overall shape of a disk defining a central axis (4) and comprises on a first surface a high number of protruding parts (6) arranged according to a peripheral circle and defined by intersecting plane surfaces which are obliquely slanted with respect to a plane corresponding to the disk. The protruding parts 6 are adjacently joined according to external (9) and internal (10) edges radially oriented with respect to the central axis (4) for forming a saw-tooth ring.
