A new class of soft functional materials, most prominently organic semiconductors such as OLEDs, are gaining commercial acceptance through their superior performance, low temperature processing, and chemical tunability. A key drawback to faster incorporation into products has been the difficulty of patterning these materials using traditional microfabrication methods. Orthogonal photolithography, which uses polymers and solvents based on fluorine chemistry, provides an easy route to realizing direct lithographic patterning of a wide variety of materials, including most organic semiconductors, on existing cleanroom equipment. An overview of the chemistry that underlies the technology will be discussed, and a variety of applications including displays and biomedical devices will be detailed.
Bio:
Dr. DeFranco graduated with his PhD in applied physics from Cornell University in 2009, after working in the research group of George Malliaras. His research focused on patterning and processing of organic semiconductor devices and in novel device architecture. While at Cornell, he was co-author on more than 20 journal articles. In 2009, he founded Orthogonal, Inc. based on the photoresist system developed in collaboration with Professor Chris Ober, an expert in photoresist and green chemistry. Dr. DeFranco is now CEO of Orthogonal, an eight person company in Rochester, NY.
