Abstract
A portable carrier (10) for storage and transportation of semiconductor slice cassettes in a clean room environment which shields the semiconductor slices from VLF air in people occupied areas includes a base (12), a pair of spring-mounted cradles (14) mounted on base (12) for supporting the semiconductor slice cassette and a cover (16) for disposal on base (12) to provide a sealed volume. Carrier (10) also includes a latch (20) for removably coupling cover (16) onto base (12). Latch (20) includes a handle (22) at the terminal end thereof to facilitate handling and transporting of carrier (10) when cover (16) is locked in place on base (12). A latch tube (24) is mounted proximate the center of base (12) and cooperates with latch (20) to couple cover (16) onto base (12). A pair of particle filters (26) are mounted on base (12) and positioned beneath cradles (14) to equalize the pressure on the interior and exterior of carrier (10) and thus reduce the pressure drop across seal (18) to zero under normal conditions. A pair of guides (28) are positioned proximate the rear of base (12) to either side thereof and outside seal (18). Guides (28) are adapted to be disposed through apertures provided in cover (16) to facilitate placement of cover (16) onto base (12) and prevent misalignment thereof.
