Abstract
Substrate loading device including a frame adapted to connect the substrate loading device to a substrate processing apparatus, the frame having a transport opening through which substrates are transported between the loading device and processing apparatus, a cassette support for holding at least one substrate cassette container, and cassette support purge ports with purge port nozzle locations disposed on the cassette support, each nozzle location being configured so that a nozzle at the nozzle location couples to at least one purge port of the substrate cassette container, wherein each nozzle location defines an interchangeable purge port nozzle interface so that different interchangeable purge port nozzles are removably mounted to respective nozzle interfaces of the nozzle locations that correspond to the different nozzle configurations of the interchangeable purge port nozzle modules, in conformance with and effecting coupling to different ports of different substrate cassette containers having different purge port characteristics.
