Method and apparatus for producing polymer and method and apparatus for producing organic film
Provided is a method and an apparatus for producing a novel polymer that is easy and convenient to control the reactivity and excellent in film thickness control and a method and an apparatus for producing an organic film. A production apparatus includes: a first means for turning a raw-material solution containing an organic compound into a mist or droplets by an atomization or a droplet-formation; a second means for carrying the mist or droplets onto a substrate using a carrier gas; and a third means for subjecting the mist or droplets to a thermal reaction by heating on the substrate. Using the production apparatus, an organic film, such as a polymer film, is formed by atomizing or forming droplets from, for example, a raw-material solution containing the organic compound, such as a monomer, delivering a mist or droplets generated by the atomization or the droplet-formation to a substrate with a carrier gas, and, after the delivery, subjecting the mist or the droplets to a thermal reaction by heating on the substrate.
