ISORG – a new company in the printed organic electronics field. Update on Liten’s start-ups. ISORG, set up in May 2010, provides disruptive technology for organic photodetectors and high-performance, large area image sensors. Its products are made from conducting and semi-conducting materials produced by the organic chemicals industry, which are deposited in liquid form using large area printing methods like rotogravure or screen printing. Isorg benefits from Liten’s portfolio of 25 patents in the printed organic electronics field and targets many markets, including industry (photometry, colorimetry, image capture), lighting, displays, medicine (imaging, analysis and monitoring systems), environment (fluid and gas monitoring), security (access control, scanners, fire detection) and consumer electronics. The company has now begun specific development work for several customers. An industrial pilot line, shared with Liten teams, is being set up on the CEA Grenoble site in preparation for its first production run in 2012. A broad spectral bandwidth photodetector A demonstrator consisting of three organic photodetectors was created with the start-up company Isorg, created by Liten in 2010. The organic electronic components in these detectors contain a mixture of two p-type and n-type semiconductors. The efficiency of the photodetectors (EQE) is greater than 50% in the visible spectrum, and since work began it has been extended to the near infrared. Its optoelectronic performance characteristics are stable over time under standard conditions. This means that the organic nature of the electronic components does not lead to premature ageing. These detectors could be used in medical radiography and industrial applications to be defined. One of the demonstrators is used to detect movement, measure the number of objects in a location, and detect a laser pointer, etc. A contactless computer keyboard using organic photodetectors is currently being developed. Note that this family of electronic components will be used to make everyday products «smarter». The PICTIC platform was set up at the end of 2010 to run trials on innovative processes for making organic electronic components and to prepare their transfer to industry. It will also be used for making prototype components for integration firms. PICTIC builds on the outcomes of the Printronics project at the Minalogic cluster. At that time, Liten acquired expertise in electronic ink formulations, organic electronic component architecture and printing processes. This helped it become one of the first laboratories in the world to master fully printed CMOS organic circuit technology. The PICTIC clean room will have an area of 600 sq. m. and accommodate various types of printing equipment, including inkjet, ultrasonic spray, screen-printing and rotogravure. These technologies will be used to print electronic functions on 320 mm x 380 mm plastic substrates.
