SUMMARY:Soft Materials Lithography Using Orthogonal Solvents and Photoresis
 ts – John De Franco\, Orthogonal Inc.
DESCRIPTION: John De Franco\,  Orthogonal\, Inc.\, Kodak Research Labs\, 
 1999 Lake Avenue\, Rochester\, NY 14650\, USA.A new class of soft function
 al materials\, most prominently organic semiconductors such as OLEDs\, are
  gaining commercial acceptance through their superior performance\, low te
 mperature processing\, and chemical tunability. A key drawback to faster i
 ncorporation into products has been the difficulty of patterning these mat
 erials using traditional microfabrication methods. Orthogonal photolithogr
 aphy\, which uses polymers and solvents based on fluorine chemistry\, prov
 ides an easy route to realizing direct lithographic patterning of a wide v
 ariety of materials\, including most organic semiconductors\, on existing 
 cleanroom equipment. An overview of the chemistry that underlies the techn
 ology will be discussed\, and a variety of applications including displays
  and biomedical devices will be detailed.Bio:Dr. DeFranco graduated with h
 is PhD in applied physics from Cornell University in 2009\, after working 
 in the research group of George Malliaras. His research focused on pattern
 ing and processing of organic semiconductor devices and in novel device ar
 chitecture. While at Cornell\, he was co-author on more than 20 journal ar
 ticles. In 2009\, he founded Orthogonal\, Inc. based on the photoresist sy
 stem developed in collaboration with Professor Chris Ober\, an expert in p
 hotoresist and green chemistry. Dr. DeFranco is now CEO of Orthogonal\, an
  eight person company in Rochester\, NY.Site web du groupe du  Dr. De Fra
