Abstract: A roll to roll, thin film manufacturing process/apparatus overcoming the shortcomings of current roll to roll processing; The roll to roll enabled cartridge is loaded with a bolt of flexible substrate. A skate couples with a cartridge, forms a seal with the cartridge's bottom aperture and drives the cartridge along a rail to an array of deposition heads. System control commands a head to mate with the cartridge top forming a seal about the variable area deposition aperture. The mating of the skate, cartridge and head form a pressure vessel wherein a film forming environment may be maintained. As the substrate advances through the deposition zone a layer is formed, bolt end to bolt end. Device growth continues from one head to another, as grown device encapsulation seal inclusive, aperture environmental seals applied, labeled cartridge is routed to dock, skate returns to process start.
