Patent ID: 7036673

Claim:
A container assembly for carrying a wafer product constituting a lot in a production line, said container assembly comprising: at least two stackable container units, each unit having: a top and a bottom opposite the top; opposite lateral sides extending between an upper lateral edge adjacent said top and a corresponding lower lateral edge adjacent said bottom; an upper attachment rail extending along each upper lateral edge of the container unit in a wafer insertion direction; and a lower attachment rail extending along each lower lateral edge of the container unit in a wafer insertion direction; wherein said top, said bottom, and said opposite lateral sides form an interior cavity; wherein each lateral side includes an outer face and an inner face and each inner face is corrugated to form a vertical array of grooves extending in the wafer insertion direction; and wherein each groove of each side is aligned with a corresponding groove of the opposing side and each set of opposing grooves forms a compartment configured to receive the waferproduct in the wafer insertion direction and hold the product; and at least two connectors for releasably connecting the container units to each other, each of said connectors connecting an upper attachment rail of one of said container units to a corresponding lower attachment rail of another of said container units thereby forming the container assembly for carrying the wafer product in said production line; wherein the compartment are uniformly spaced when said units are aggregated to each other and retained by said conductors.
