Publication number: 20100084081Abstract: A method for fabricating organic optoelectronics multi-layer devices is disclosed. A polydimethylsiloxane (PDMS) surface is pretreated with an organic solvent and used to directly form a uniform optoelectrical thin-film from organic solution by spin coating. The optoelectrical thin-film films that are formed on the PDMS surface are easily transferable to any substrate by a slight, externally applied force for providing conformal contact with a target substrate and thermal annealing, depending on the polymers to be transferred. Pretreatment of the PDMS surface with the organic solvent combined with a dry transfer process provides an easier way to cascade polymer architecture fabrication. In addition, the method increases the performance of various types of organic photo electronics, and permits an extension of the types of research that can be performed in the field of photo electronics.Type: ApplicationFiled: August 6, 2009Publication date: April 8, 2010Applicant: Academia SinicaInventors: Chih-Wei Chu, Zhong-Yo Ho
