The wafers/cells are transferred between the single process steps either manually or via Montrac system in specially developed SCHMID Carriers. The full Carriers are positioned in the Loader in a row and moved to the transfer position. Here the wafers/cells are moved out of the carrier cases via an index system and subsequently conveyed to the process equipment. In reverse the Unloader receives the wafers/cells and assures a constant loading of the SCHMID Carriers. For this the wafers/cells are synchronized in rows on speed controlled conveyor belts and successively stored in the empty carrier cases via an index system.
