ABSTRACT:
A rotating and translating support assembly for receiving a front-opening pod according to applicable SEMI standards, and thereafter rotating the pod to a desired orientation. In this way, a number of pods may be received at interface ports of a minienvironment, and each of the pods and ports may be angled toward and aligned with a single, 2-arm pick and place robot. In a preferred embodiment of the present invention, the rotating and translating support assembly comprises a plate rotationally and translationally mounted on a shelf extending from the minienvironment adjacent to a front-opening interface port. In one embodiment, the support plate may be mounted on a shaft attached to a rotating assembly, such as for example a worm and drive gear. The rotating assembly may in turn be mounted on a translating assembly, such as for example a carriage riding on a lead screw. The rotating and translating assemblies may be controlled by a host computer, so as to rotate and translate a pod received on the support plate, to align the pod with an interface port which may be provided at an angle with respect to the front of the minienvironment.
