Abstract:
A device for attaching a transfer container, which accommodates a target substrate, to a port of a semiconductor processing apparatus, the transfer container having on a front side an opening portion to be aligned with the port, and on a bottom side a first engaging portion, the device comprising:a table having a mount portion on an upper side, on which the transfer container is placed, and an opening portion formed at a position corresponding to the first engaging portion; a link swingably supported on a lower side of the table about a first rotational axis used as a center; a clamp swingably supported by the link about a second rotational axis used as a center, and having a second engaging portion, which projects upward from the table through the opening portion to engage with the first engaging portion when the clamp swings in a first direction; a first actuator configured to apply a swing-driving force to the clamp; and a control structure configured to control swing of the link and the clamp, and set such that, when the first actuator applies a swing-driving force to the clamp in the first direction, the clamp swings relative to the link about the second rotational axis used as a center in a first period until the second engaging portion enters the first engaging portion, and then the link swings along with the clamp relative to the table about the first rotational axis used as a center, thereby moving the clamp downward for the second engaging portion to catch the first engaging portion in a second period following the first period.
