COMPOSITE SUBSTRATE CONTAINER WITH OVERMOLDED WAFER RETAINER

摘要

An overmolded wafer retaining structure for engaging the edges of wafers in a wafer container. The overmolded wafer retainer includes a base portion and an overmolded portion. The overmolded portion is injection molded onto the base portion to form a hermetic bond without need for external fasteners or adhesive. The wafer retainer is situated in a wafer container such as a standard mechanical interface (SMIF) pod or a front opening unified pod (FOUP) so that when the door is mounted to the container to form a closure, the retainer is brought into contact with an edge of the wafer or wafers.
