ABSTRACT:
The present invention comprises a load port for providing access to an article that is stored in a container having a container door removably coupled to a container shell. The load port preferably loads/unloads a container directly from a container transport system. In one embodiment, the load port includes a plate having an opening, a container support plate, a drive assembly for moving the support plate vertically and a shroud to partially enclose the opening. The shroud, which may be affixed to the mounting plate, has an open top and bottom. The shroud contains a mechanism for retaining the container shell at a controllable height. During operation, a container is raised from the transport system into the shroud until the container shell is retained by the mechanism. After the container shell is uncoupled from the container door, the container support plate is lowered until the article is accessible through the opening. The container shell remains located at the controllable height. The container shell, in combination with the shroud, creates a mini-environment isolating the article from ambient conditions in the fabrication facility.
