ABSTRACT:
A roll to roll, film forming system overcoming the shortcomings of current roll to roll processing is presented; The roll to roll enabled cartridge is loaded with a bolt of fresh 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. A head mates with the cartridge top forming a pressure seal around 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 past the deposition aperture a layer is formed, potentially from 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 system start.
