Proof of Concept
CPI provides small scale (100-150mm substrate size) glove boxes with spin coating / evaporation technology that supports material and device design feasibilty studies.
These systems focus on quick turnaround, proof of concept studies where the onus is on understanding the material and electrical characteristics, thereby aiding development of the device structure by speeding up process development and aid troubleshooting. The systems are typically manually loaded by the operator and are situated in a Class 1000 clean room environment.
In order to scale up an optimised material set or device design, CPI offers an OLED/OPV prototyping line situated in a Class 100 clean room environment. Here the emphasis is on ensuring optimised manufacturing protocols. Substrates are transferred within dedicated processing cassettes with manual intervention kept to a minimum. Minimising defectivity within an OLED/OPV structure is a pre-requisite in guaranteeing device yield as the technology scales up to larger substrate sizes. A typical lighting structure can consist of 8-10 layers with layer thicknesses of < 50nm. CPI’s pilot prouction scale system is dedicated to processing both air sensitive and non air sensitive material sets for the production of devices on substrates up to 200mm2. The tool can accommodate the processing of both small molecule and solution based polymer materials and includes both slot die and spin coating techniques. Evaporation technology provides both inorganic cathode and organic small molecule capability. Device performance and lifetime are enhanced by the use of a dedicated encapsulation module to apply getters and adhesives. Fully automated robotic control, cassette to cassette handling and HEPA filtered laminar flow modules provide a unique environment to support high yield, low defect device production.
The high resolution wide area line also has the ability to handle substrates of size 8 inch, 12 inch and GEN 2 scale (370mm x 470mm) The pilot line features sputter, dry etch, wet etch and cleaning capability and provides the ability to produce high quality lighting devices at pilot-production scale.
Roll to Roll Production
CPI also provides further scale up capability in the form of a 300mm web roll to roll coater for the printing of a range of organic material sets. The system comprises of both slot die and screen printing capabilities, with options to upgrade to 500mm web width and to incorporate other printing techniques such as reverse gravure.
The roll to roll machine houses a complementary encapsulation module, configured to allow the organic devices manufactured within the coater to be laminated with a barrier film. The tool provides protection to the device from water and oxygen ingress, both of which are known to be detrimental to device performance and lifetime.
