Integrated Organic Circuits and Technology for Large Area Optoelectronic Applications

Organic semiconductors can be deposited at near-room temperatures, enabling the creation of electronic and optoelectronic devices on virtually any substrate. This unique technology makes possible the fabrication of large-area, mechanically flexible optoelectronics, such as conformable displays or image sensors. To realize these systems, an integrated approach to fabrication of organic optoelectronics is necessary.

A near-room temperature (<95 degrees C), scalable process has been developed, using conventional photolithography and inkjet printing. This process produces integrated organic field effect transistors (OFETs) and organic photoconductors (OPDs) on a single substrate.

Typical device characteristics for an integrated OFET are studied. As a proof of concept, a 4x4 active-matrix imager was created using the process and was demonstrated to correctly image patterns.
