ABSTRACT:
Organic films can be annealed by exposure to a solvent vapor. The solvent vapor annealing renders the organic film insoluble even in a solvent of a solution from which it was deposited. This enables deposition of two or more organic films in sequence without having one deposition alter an underlying organic film. Devices can be easily fabricated with organic films annealed in this manner when no other solution processing method is possible.
