ABSTRACT:
An injection molded container for storing and transporting wafers includes a base having a wafer area upon which to place a stack of a plurality of wafers. A protective wall surrounds the wafer area, and extends upward, having a first perimeter at the base and a second perimeter at a top wall extremity that is greater than the first perimeter, resulting in the wall being positioned with a draft angle to a line perpendicular to a plane of the base so as to facilitate removal of the container from an injection mold. This invention provides a plurality of wafer positioning columns, each having a surface with a line of contact rising perpendicular to the plane of the base. The lines of contact are positioned so as to restrict movement of a stack of wafers placed in the container.
