ABSTRACT:
A method of fabricating semiconductor devices using ink-jet printing is provided to directly deposit patterned polymer films to create OLED's and other semiconductor devices. The luminescence of poly-vinylcarbazol (PVK) films, with dyes of coumarin 6 (C6), coumarin 47 (C47), and nile red was similar to that of films of the same composition deposited by spin-coating. Light emitting diodes with low turn-on voltages were also fabricated in PVK doped with C6 deposited by ink-jet printing.
