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).
