Our machine, Camara Oscura, could economically manufacture a wide variety of thin-film electronic devices and do it in high volumes. Applications of Thin-Film devices formed or printed on flexible substrates include:
OLED SCREENS - SOLAR CELLS - SENSORS - BATTERIES - CLOTHES - ROBOTS
The present invention has been made in view of the lack within the industry of a pressure vessel that robustly enables versatile roll-to-roll processing of thin film electronics on a flexible substrate. The object is to provide a pressure vessel that enables not only roll to roll processing but also provides for scale-able configurations for assembly-line production facilities for the ubiquitous manufacture of said electronics. The core aspect of the invention provides a pressure vessel for applying varying pressure working processes for the formation of a plurality of device layers on the flexible substrate via multiple roll-to-roll sequential, non-sequential processing steps or hybrids of these. Moreover, the cartridge component of the pressure vessel allows for substrates to be loaded, conveyed, processed, sealed, stored, and transported in a single container.
Camara Oscura is a roll-to-roll film forming system. In its simplest form this dynamically configure-able, controlled environment system consists of a rail, a skate, a cartridge, and a station. A station is comprised of one or more heads. The rail is a trackway used by a skate for advancing a skate to and coupling with a cartridge, advancing this assembly to a station, and aligning the skate/cartridge assembly with a head. The roll-to-roll enabled cartridge containing a bolt of flexible substrate joins a head, creating a film forming environment. Within the cartridge the substrate advances past the deposition window which penetrates the top of the cartridge and material delivery systems mounted in the head deposit films on the substrate via the deposition window. Film formation may take place anywhere on the substrate as it moves via roll-to-roll action through this deposition zone.
