The present invention comprises a fully automated, fabrication compliant furnace with the advantages of the horizontal most of the advantages of the vertical furnace. One embodiment of the present invention is that it implements a multi-degree motion robot arm to move wafers from a loading area to a WIP station where the wafer are then loaded into wafer boats on a rotating cantilever system or directly onto a specialized and reconfigurable paddle designed to hold wafers: The wafers may be loaded in the horizontal processing position as well as the vertical processing position. Multiple levels of the semi-toroidal horizontal processors allow for multiple batches of wafers to be loaded, processed, cooled, and unloaded by the robot arm. The present invention reduces the footprint of the traditional horizontal or vertical furnaces, increases capacity and throughput, and allows for direct tube transfer.
