Abstract
A bellows clamp actuator (10) is provided for holding a semiconductor slice cassette (14) within a container (12). The bellows clamp actuator (10) has a V-bar clamp (40), a hollow bellows (38) and a mounting device (56). The bellows clamp actuator (10) is mounted to the door (18) of the container (12). A hole (72) connects the chamber (67) with the atmosphere external the container (12). When a vacuum is drawn within the container (12), the pressure difference causes the bellows (38) to extend and the V-bar clamp (40) to contact and secure the cassette (14) against the vertical guide posts (36).
