Abstract
A three-component tray-type packaging unit for semiconductor wafers, compatible with automatic equipment, includes a wafer carrier enclosed between a tub-shaped lower portion for receiving the wafer carrier and a matching lid. The wafers are fixed at four contact points-namely, in the wafer carrier by two rows of spring tongues arranged tangentially with respect to the wafer, and in the matching lid by two rows of inwardly projecting retention cones.
